What is Qbasic?Microsoft QBasic(MicrosoftQuick Beginners All purpose Symbolic Instruction Code) is anIDEandinterpreter for a variant of theBASIC programming languagewhich is based onQuickBASIC. Code entered into the IDE is compiled to an intermediate form, and this intermediate form is immediately interpreted on demand within the IDE.

Qbasic ExamplesQBasic came complete with four pre-written example programs. These were "Nibbles, a variant of theSnake game; "Gorillas", anArtillery game; MONEY MANAGER", a personal finance manager; and "RemLine, a GW-BASIC code line-number-removing program

The Qbasic Interface and its Parts

Name of current programThe file name of the current program is displayed near the top of the screen in the center. You can change the name by selecting"Save As"on the"File"menu.

Immediately execute a commandQBasic provides a way to execute a command without running the current program. To do so, select the bottom window (under"immediate") and enter a command, then pressEnter.
