PML Basics Part 1 - 10-25-2006Alright expert and cvitte71, I did promise to get more involve with pdmsworld. So here we go. I will start adding new thread for those who want to learn PML, starting with the basics (PML 1) working my way to PML2, forms, functions, you get the idea. To start out, I wanted to introduce the Dollar $ symbol and its meanings $M = Runs a macro in pdms $! = Evaluate a varieble $. = Terminates a macro $S = Defines a synonym $G = Defines a global synonym $S- = Turns synonyms off $S+ = Turns synonyms On $QS = Queary's the synonyms $H = Help $Q = Another syntax help $P = Prints a line to your command line $$ = Adds a $ symbol $D = Default argument value $* = Comment line $( = Starts a comment block $) = Ends a comment block To turn the pml trace on and off I use $R To turn trace Off $R6 To turn trace On $R109 Another neat trick that I like to use, especially when using the trace is ALPHA REQ CLEAR (I will get more into this as I add more and more treads) This command cleans your command line. I really hope everyone gets involve and If i miss anything please added to the tread.A query on usage in the field: how much do you use the $ comments (either $* or $(...$) )? (For those of you at the ISEITs this is to do with Published PML...) I want to be able to strip comments when publishing the PML, and am wondering just how much trouble to go to with wierdly nested and hidden comments! (I will never mangle anything, but might not strip all the comments if you do really odd things)I use the $* comments as much as possible. Specially because I'm the kind of person who will write a macro and forget about it and 6 months later someone is asking me to add some new function to the macro. I try to add as much comments for my own personal benefit. If you are new to pml and you want to make life easier. I suggest you try to comment as much as possible. Also, name you macros something that will make since 6months to even years from now. I have spend hours, days even months writing macros only to misplace them. By adding as much comments, you are not only making your life easier but your employeer as well. This go back to the ISEIT meeting.JCont....mate its simply awesome.....very useful...please keep it up!.... I reckon better add the ALPHA LOG command...where you can take ur logs to a file and not flood ur command line :)--------------------------------------------------------------------------------------------------------------------Yes I agree. When using the Tracking, you might want to use the alpha log command first. Try this. Alpha log /C:/test.txt over By adding the over, I am overwriting any file with the name Test.txt Turn trace on $R6 Than, using the pull downs Modify > Name The modify name form will come up and your command line filled with text. $R To turn off the Trace Alpha log end To end the log Open the .txt file and check out some of the code. That is how I learn pml, by reading aveva's code. Just a note: You are only allowed to have one log file open at the time. Another option will be to use Alpha Files. I'll get to that later.I just found this and I wanted to pass it on....Enjoy $R 1 = Tracing to shell window (default) 2 = Tracing to requests window 4 = Tracing of only input lines executed 8 = Tracing of all input lines 16 = Tracing without $ expresion (default off) 32 = Tracing includes line numbers 64 = Tracing of macro/function changes 100 = General Debugging 102 = capture trace in ALPHA LOGCan also do $HR at the command line to get all options for $R--------------------------------------------------------------------------------------------------------------------Quote:Originally Posted by TimSharrock A query on usage in the field: how much do you use the $ comments (either $* or $(...$) )?(For those of you at the ISEITs this is to do with Published PML...) I want to be able to strip comments when publishing the PML, and am wondering just how much trouble to go to with wierdly nested and hidden comments! (I will never mangle anything, but might not strip all the comments if you do really odd things) Hello Tim, I use $( and $) for large blocks of comments or for quick trouble shooting. But for individual lines of code / comments, I will normally use -- because I do not need to hold down the SHIFT key to get the -- to appear (quicker commenting for single lines). From your personal opinion, is there a preference between $* and -- ? Does one single-line commenting method work better than the other? Just curious ... Have a Blessed DayIf I do not remember wrong, you cannot use -- for inline comments where you can use the $* syntax. like: handle any $* Taking care of a problem. If I remember correctly you cannot do this with -endhandle I recall reading somewhere that -- can only be used for commenting whole lines.=====================================================================Quote:Originally Posted by TBack If I do not remember wrong, you cannot use -- for inline comments where you can use the $* syntax. yes that is the case.Quote:Originally Posted by proverbs3:6 From your personal opinion, is there a preference between $* and -- ? Does one single-line commenting method work better than the other? Just curious ... at the start of the line they are treated identically, so no preference This is the macro I am using to test comments so far - I have lots more odd things to add!Code:$P this macro tests comments in various formats $* $P this is an ordinary one-line comment $P this line is not a comment -- $P this is a new-style comment $P this line is not a comment either $( $P a short 'multi-line' comment $) $P I am not a comment - I am a free line! $( $P a long multi-line comment $P yes, I mean it$) $P now to test some combinations $P start a new-style -- in the middle of a $P $P start an old-style $* in the middle of a line $P embed a multi-line $(like this$) in the middle of a line $P try hiding a multi-line with old-style $* $( $P I wonder if this will come out $* $) $P try hiding a multi-line with new-style -- $( $P I wonder if this will come out instead -- $) $p what about the end of a multiline? $( $P this is within a multi-line $* $) $P this is after a hidden closer $P this is at the endI didn't know I could comment out part of a line with the $*. !! awesome!!!(#17)That is the beauty of using the $* comment syntax. You can write them on the same line as the actual code.Hi gentlemen, I am used to run a macro loaded with my favourite synonyms when I start PDMS. So I tried to use the command $QS as I saw it in the first post. Now I see in command window the list and I would like to get clear something. There are synonyms with $S1 before the synonym description. Example : $S1 AA = add all within volu ce $S1 Then I have here synonyms with $S0 (all my syns + some more). Example : $S0 FGF =new fla choo all new gask choo all new fla choo all (short sequence for inserting pair of flanges) And then finally there are some synonyms with $SU1 for running a macro. Example : $SU1 CALLE =$M/%PDMSUI%/DES/EQUI/$S1 I don't understand the difference between $S0, $S1, $SU1. Is it supposed to be an argument?Are not arguments in general $n - without 'S'? What does it actually do? And why it says : (47,33) CP: Illegal macro format When I try to run the macro for myself (in this case : $M/%PDMSUI%/DES/EQUI/$S1 )?One question... Why "$*" and "--" are not equivalent? "$*" works any position in the line, and "--" works only at the beggining of the line. Why AVEVA designed the comment like that? Any reason? Possible to use $R5 /FILE.namePML Basics Part 2 (Creating an Array) - 10-25-2006What is an Array? The simple answer to me would be a collection. How to create an Array !Array = Array() This is an empty variable but it has been defined as an array Adding to the array Type 1 !Array[1] = 'BOB' !Array[2] = 'GEORGE' !Array[3] = 'KELLY' Type 2 !Array.Append('BOB') !Array.Append('GEORGE') !Array.Append('KELLY') q var !Array Other Command to know when using an array !Array.Clear() !Array.Size() !Array.Sort() !Array.SortUnique() !Array.Unique() You can find out more in the PDMS Manual, Search Array Objects.wats the difference between type1 and type2......sorry am just starting to learn PML..so forgive me if im asking sumthing verryy basic! Also I was thinking if u can put some treads with examples......like 1. How can we assign values to elements using PML...e.g. If I have to assign pspec /A300 TO ALL PIPES WITH BORE SIZE 100 2. How do we collect elements and run a macro on them...e.g. collect ALL brances under zone / 10LAB and set/change Ispec to /HC and so on.....What is the difference between type1 and type2. Now, they are not called type1 and 2, I just added that so everyone can see that you can do more that one way. An array is a collection when you use the [ ] and specify a number, you are telling the exact order you want that item to be in. For example: !Array[1] = !!CE I am adding my current element to the first member of the array When I use type2 !Array.Append(!!CE) I am simply adding my current element to the list (The end of the list)Now, you added 2 questions. I believe that cvitte71 has a hot tread about collections. In order to do what you are asking for we are going to need to use a loop. I'm going to be posting another PML Basics (Loop) and I'll use your questions as examples. Check out my new thread on loops PML Basics Part 3 (Creating a Loop) I added you question as the examples.PML Basics Part 3 (Creating a Loop) - 10-26-2006Here we go again. Out of everything that I have learn about pml, I had the most difficulty learning Loops. I didn't understand them, finally after many mistakes I got a handle on loops. What is a loop? Its a series of commands that will continue to happen until the loop is broken. Do This starts a loop, now one of my first mistakes was that I didn't specify the number of times I wanted the loop to run and I didn't know how to break the command Enddo For every "Do" you must have an "Enddo" Now I know I haven't covered collections but you can check out a nice sticky threat cvitte71 has started. So lets do a simple macro. This macro will collect all sections, check the gtype to make sure its correct and print any sections that have the incorrect gtype. var !Coll coll all (SCTN GENSEC) with (Gtype of Catref neq Gtype of Sctn) for $!!CE I know this is not PML2; lets get the basics out first. Do !x from 1 to !Coll.Size() Now, what does this line mean? I already explained that the "Do" starts the loop. The second parts "!x", is a number any number. In this case from 1 to !Coll.size(). In other words, the first time the loop runs, !x will equal 1 then 2 so on until it reaches ! Coll.Size() What is !coll.size()? Its the number of items inside the !coll array. $P $!Coll[$!x] has the wrong Gtype $p is the print command $!Coll[$!x] mean $!Coll[1] which is the first item in the collection Enddo$********************************************** with out the comments $********************************************** var !Coll coll all (SCTN GENSEC) with (Gtype of Catref neq Gtype of Sctn) for $!!CE Do !x from 1 to !Coll.Size() $P $!Coll[$!x] has the wrong GtypeEnddo I'll add more example later today.Hello, you can also use: var !Coll coll all (SCTN GENSEC) with (Gtype of Catref neq Gtype of Sctn) for $!!CE Do !x indices !Coll $P $!Coll[$!x] has the wrong Gtype Enddo or Do !x values !Coll $P $!x has the wrong Gtype EnddoYes Thank you bh0nst. Keep them coming. When you use the: Do !x indices !Coll !X is still a number But when you use: Do !x values !Coll !x is now the item or an elementMore examples, this is a request by 786PDMS 1. How can we assign values to elements using PML...e.g. If you have to assign pspec /A300 TO ALL PIPE WITH BORE SIZE 100 First, You have to do a collection for all Pipe with bore eq 100. Again, cvitte71 has a great thread on collections going on. Var !PIPE COLL ALL (PIPE) WITH (PARAM[1] OF CATREF OF SPCO EQ 100) FOR $!!CE Do !x indices !PIPE $!PIPE[$!x] PSPEC /A300 Handle Any $* Why did I add a Handle, the pipe could of been claim or locked, this way the macro will continue $pError on $!PIPE[$!x] $*Printing the error so I can identify the element that the pspec was not assigned EndHandle Enddo 2. How do we collect elements and run a macro on them...e.g. collect ALL brances under zone / 10LAB and set/change Ispec to /HCVar !BRANCH COLL ALL BRAN FOR /10LAB Do !y indices !BRANCH $!BRANCH[$!y] Ispec /HC Handle any $pError on $!BRANCH[$!y] EndHandle EnddoAre you going to examine OBJECTS, especially the COLLECTION OBJECT. And the use of this object? Like you pointed out in your thread, the other collections thread explores multiple ways to create the collection using both PML1 and PML2. Very intriquing. The multiplicities of options in using PML can be daunting.--------------------------------------------------------------------------------------------------Yes, I'll start getting more into object collect & object collections. Here is another example using a different type of collection !BRANCH = !!CollectAllFor('BRAN', '', !!CE) Do !y indices !BRANCH $!BRANCH[$!y] Ispec /HC Handle any $pError on $!BRANCH[$!y] EndHandle Enddo PDMSGuru, I'm not a piping designer (my back ground is structural) and I got the information on how to queary the pipe bore from a previous threat you answered, could you double check my previous collection. I don't want to give anyone the wrong information. Specially since we are not running pdms out of the box, we have customize pdms to an extreme.================================================================As you get an array of element references directly by using the CollectAllFor function you could also assign the attribute value without first jumping to the element, like: !BRANCH = !!CollectAllFor('BRAN', '', !!CE) Do !y indices !BRANCH !BRANCH[!y].Ispec = /HC Handle any $p Error on $!BRANCH[$!y] EndHandle Enddo The selected element would in this example remain the same also while running through the loop.jcont20, Your collection would now have worked. Var !PIPE COLL ALL (PIPE) WITH (PARAM[1] OF CATREF OF SPCO EQ 100) FOR $!!CE PIPE Elements do not have CATREF's, in addition, the BORE ATT on a PIPE element is not even an intelligent one.A way I could accomplish this is Var !PIPE COLL ALL BRAN MEM WITH (p1 bor EQ 100) FOR CE Collecting Branch members themselves is the best way I find to work with piping components. Heads and tails may change on branches, and sometimes they don't even reflect what's in the pipe, a head bore may be 100, then the first mem is a reducer, the rest of the branch might then be 150. so working with branch members is better in my humble opinion. Next, notice I asked for the p1 bore, this guarantees me that I will add an element with at least one side of it matching my criteria, I could add more criteria to guarantee that I get anything that has 100 as a bore, p1, p2 , p3 etc. But by asking for catalogue parameters, I'm assuming that my catalogue administrator hasn't done anything silly with the first parameter. An event that has undone me in the past. Also, to clean it up a bit, you don't need the $!!CE, just CE will do. Tip: on anything that has a SPRE with a CATREF, the CATREF is also available for query from that element. So instead of CATREF of SPRE, (I would not say SPCO, as that is an element, and not a reference), you could just call the CATREF, it is a pseudo attribute. I've heard some really good things about you jcont20, someone that spoke with you at the Americas Conference in the US says you are doing some great things with Ring Plates. Your company is lucky to have you, and so is PDMSWORLD. Keep up these great posts. I'll comment when you invite me to. I really enjoy reading them. Thanks for asking me to pitch in, I am honored.Hi JCont20, Thank u 4 explaining things much better than the manuals :)....i did try ur and others code and its a good practice as a start...for one of our real projects i have to rename ALL zones with name contaioning -PREM to -PRELIM e.g. Zone /16CS-UHA-21.4-PREM needs to be renamed to /16CS-UHA-21.4-PRELIM please review my code below and guide me how to rename the zones as required above...i belive my collection is ok..but only the rename part i need to fix with ur help define function !!APMCheckLevel() Var !PRZONE COLL ALL (ZONE) WITH (MATCHW(NAME,'*-PREM*') ) FOR $!!CE Do !y indices !PRZONE $!PRZONE[$!y] RENAME ....HOW????? Handle any $pError on $!przone[$!y] EndHandle Enddo endfunctionI'm not in front of PDMS at present (can't afford the software at home)... So I can't check this... Check this in a limited area before running.....Define Function !!APMCheckLevel() var !PRZone coll all Zone with (Match (Name of Zone, 'PREM') gt 0) for ce $* I like Match instead of Matchwild Do !z values !PRZone $* Used Values instead of Index... $!z !NewName = !z.Before('PREM') + 'PRELIM' $* Will take current name z, strip off PREM, and add PRELIM Rename $!NewName $p $!z renamed to $!NewName $*Just Prints the old and new to command line EndDo EndFunctionCan be done in one row...Quote:Originally Posted by 786PDMS Do !y indices !PRZONE !PRZONE[!y].Dbref().Name = !PRZONE[!y].Dbref().Name.Replace('-PREM','-PRELIM') Handle any $p Error on $!przone[$!y] EndHandle EnddoGuyz thankz a bunch..... @Tback tried ur code and it works beautiful!!..... @ccotton i'll also try urs and see how it goes....just wondering wats the diff b/w Match and MatchW Do values and Do IndicesQuote:Originally Posted by 786PDMS just wondering wats the diff b/w Match and MatchW Do values and Do Indices Match(NAME OF ZONE, |ABC|)NEQ(0) $*If somewhere in the name of the zone the letters ABC appear then this expression is True Match(NAME OF ZONE, |ABC|)EQ(0) $*If the letters ABC does not appear then the expression is TrueMatchw(NAME OF ZONE, |*ABC|) $*Let say the name is /123-ABC, then this expression is True $*Let say the name is /ABC-123, then this expression is False.

Hi I'm new in the forum and I hope somebody can help me because I want to make an array checker, that compare every element of the array and delete the elements repeated from the array. HELLO, there is especial commands for work with arrays in the PDMS manuals. you can use "UNIQUE" for delete the duplicate values. more info: PDMS Software Customisation Guide 6-9 Version 11.6SP1 bye.Hi JCont20 The GTYPE macro is brilliant...one of my colleuges was just talking about that discrepancy the other day... Would it be much mor ework to actually correct that discrepancy ?SURE, YOU CAN FIX IT. I HAVE A SCHEDULE TASK THAT TAKES CARE OF IT FOR THE USER. WORKS SOMETHING LIKE THIS.Code:!SCTN = !!CollectAllFor('SCTN' , 'Gtype of sctn neq Gtype of Catref', World) Do !x INDICE !SCTN IF !SCTN[$!x].CATREF.UNSET() Then $P$!SCTN[$!X].NAME is unset skip EndIf !SCTN[$!x].GTYPE = !SCTN[$!x].CATREF.GTYPE HANDLE ANY $PError with sctn $!SCTN[$!x].Name ENDHANDLE ENDDORegarding JCont20's macro...var !Coll coll all (SCTN GENSEC) with (Gtype of Catref neq Gtype of Sctn) for $!!CE Do !x from 1 to !Coll.Size() $P $!Coll[$!x] has the wrong Gtype Enddo Just starting to look at PML and macros.. Could anyone tell me if i'm correct on my assumptions.. To break down the first line... var !Coll - this defines a local object of this name coll - is this a commmand to make a collection ? $!!CE - this is a global object of this name $P $!Coll[$!x] has the wrong Gtype - what do the square brackets do [] ? Thanks for the help...Neil!Coll is array of sections's and gensecs's names whose gtype not equal gtype of catref. It is collection from current element ($!!CE). Coll - you are right, this is command to make collection and to store it in array !Coll. $!!CE gives reference number of CE. $P $!Coll[$!x] - in [] number of array's element is indicates, in this case $!x is number of current cycle of the loop.Alright, Sorry I have been gone for so long, I have been extremely busy like everyone else in the PDMS community. Here is a small simple macro to using a do loop. Multiple copy command for draftCode:Define Function !!MultiCopy() !CS = Current Session If !CS.Module().NEq('DRAFT') Then return Enddo !element = !!ce Do New $!Element.Type copy prev On ID @ Handle Any refresh returnEndHandle Enddo EndFunctionHello! Im a newbie and Im trying to make a loop that collects the names of all sheets in a specific regi and writes them to a logfile. Can anybody tell me what im doing wrong? /PIPELAYOUT/ var !sheename collect all SHEE for REGI !File = object file('C:/Plots/names.log') !Array = object Array() var !sheename collect all SHEE for REGI do !i INDEX !sheename VAR 1 NAME $!Array.Append($V1) enddo !File.writefile('overwrite',!Array) The array dont seem to be accessible inside the do loop Change " $!Array.Append($V1)" to "!Array.Append(V1)" and you should be OK. Thanks for the quick response. But it didnt work. Quite confusing with all the $ !. This is my code at the moment ONERROR CONTINUE /PIPELAYOUT/ !File = object file('C:/Plots/names.log') !Array = object Array() var !sheename collect all SHEE for REGI do !i INDEX !sheename VAR 1 NAME !Array.Append(V1) enddo !File.writefile('overwrite',!Array) Slight modification then. Change your do-loop to this: do !i INDEX !sheename !name = name !Array.Append(!name) enddo thanks I thank for all this kind of posts, because i'm getting startiing in PML and it's very usefull to get this info...Quote:Originally Posted by dit02lbt Thanks for the quick response.

Now I want to start getting in to expressions and If statements. Before we get started writing our own expressions. I remember when I was first learning expressions, I turn to the manuals. If you have a chance, please check it out. But, since I know most people don't really open the manual, I'm going to post the part on expressions. we need to know some Operator: 1. 2. 3. 4. 5. 6. 7. Brackets () */ +EQ, NEQ, LT, LE, GE, GT NOT AND ORNow, when writing an expression, think back to high school math or even middle school math when you learn how to solve nested expressions. (4 * (POWER(PARA[1], 2) + POWER(PARA[2] , 2) ) You have several different types of expressions: Logical expressions PDMS attributes Logical constants TRUE, ON, YES for true FALSE, OFF, NO for false Logical Operators Conparator operators (EQ, NEQ, LT, GT, LEQ, GEQ) Boolean operators (NOT, AND, OR) Logical functions BADREF DEFINED, UNDEFINED CREATE DELETED EMPTY MATCHWILD MODIFIED UNSET VLOGICAL PDMS attributes Ex: XLEN YLEN POHE POSITION ORIENTATION The keyword PI(3,142) Numeric operatorLogical array expressions + Add - Subtract * Multiply / Divide Numeric function I'm not going to list all of them but some of them are: ABS, ACOS, ASIN, ATAN, SIN, COS, TAN, MATCH, MAX, SQRT..Real expressions See numeric funtions Real array expressions Text expressions A text string PDMS attributes Text operators Text fuctions__________________________________________________ _________________ Ok, lets start creating some If statements using some of this expressions. This is an example I like to use a lot. When users descover that they can create sctns using syntax, sometimes they forget to change all the attributes. One of those attributes will be the GTYPE. So a simple expression will be: !Catref = Gtype of Catref !Sctn = Gtype of Sctn If (!Catref neq !Sctn) Then Gtype $!Catref Handle any $* I try to add a handle anywhere I think I might have a problem, in this case, the section could be claim EndHandle Else $PSctn has correct Gtype EndIf The If statements can get nasty, here is a simple one. If !!CE.Type.Eq('PIPE') or !!CE.Type.Eq('STRU') or !!CE.Type.Eq('EQUI) Then or If ((Type of CE eq 'PIPE') or (Type of CE eq 'STRU') or (Type of CE eq 'EQUI')) Then Its, getting late and my wife is ready to use the computer. If anyone has any request or question, please ask. I'll continue this tomorrow.I tend not to use the !!ce as you have to navigate to it within PDMS, I find it safer to create say an array of items (which will be dbrefs) then query or assign accordingly e.g. $* assign some variables !File = object file('%pdmsuser%/log/logfile.log') !Array = object Array() $* collect some items !Coll = !!collectallfor('elbo','',world) $* action the collection Do !A indices !Coll If (!Coll[$!A].catref.upcase() ne 'XXXX') then $P we missed this one -- $!Coll[$!A] !Array.appned(!Coll[$!A].name) Else some other action Endif Endoo $* see if we found any data errors, if so output to a file and advise user If (!Array.size() gt 0)thne $P we have an out put error/log file !File.writefile('overwrite',!Array) Else $P it all went well Endif $* get user to acknowledge the macro has finished !!Alert.message('You have now finished')Hello, I'm a new PDMS/PML user, I'm just learning. Can anybody help me in macro writing? I would like to make a macro in PML1, which is counts the valves and elbows in a current site and write the result in a file. I try to make it since two days, but it isn't works. Please help me, if you can ... I'd use the inbuilt "collect" function !Valve = !!collectallfor('valv','',!!ce) --- !!ce ==> ce, in this case the site you want to collect valves from !Elbow = !!collectallfor('elbo','',!!ce) --- !!ce ==> ce, in this case the site you want to collect elbows from !ValveSize = !Valve.size() !ElbowSize = ....... Do the same for other components then create an array !Items[1] = ('number of valves ' & !ValveSize) !Items[2] = ('number of elbows & !ElbowSize) etc !File = object file('%pdmsuser%/filename.out') !File.writefile('overwrite',!Items)If you want to do it for a number of sites then collect the sites into an array e.g. !Sites = !!collectallfor('site','',world) and create a do loop Do !A indices !Sites $!Sites[$!A]
