Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

The {{KW|SYSTEM}} statement immediately closes a program and in DOS and can avoid returning to the QBasic [[IDE]].
|
|
|
|
|
|
{{PageSyntax}}
|
|
:'''SYSTEM''' [return_code%]
|
|
|
|
|
|
{{Parameters}}
|
|
* QB64 allows a ''code'' number to be used after SYSTEM to be read in another program module by the [[SHELL]] or [[_SHELLHIDE]] functions.
|
|
|
|
|
|
''Usage:''
|
|
* This command should be used to close a program quickly instead of pausing with [[END]] or nothing at all.
|
|
* A code can be added after the statement to send a value to the [[SHELL (function)]] or [[_SHELLHIDE]] function in another module.
|
|
* If a program BAS module is run from the IDE, stopped by Ctrl-Break or an error occurs the QB program will exit to the [[IDE]].
|
|
* In '''QB64''' SYSTEM ends the program and closes the window immediately. The last screen image may not be displayed.
|
|
* '''Qbasic BAS files can be run like compiled programs without returning to the [[IDE]] when [[SYSTEM]] is used to [[END|end]] them!'''
|
|
* To run a QuickBasic program without the [[IDE]] use the following [[DOS]] command line: {{text|QB.EXE /L /RUN filename.BAS|green}}
