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.

|
|
* '''QB64 ignores DECLARE statements, so define the parameter [[TYPE]]s in the SUB procedure!'''
|
|
* Parameters MUST be placed in parenthesis separated by commas when necessary.
|
|
* Empty parenthesis are required when no parameters are used.
|
|
* Declarations should be placed at the top of the main program code after {{KW|Metacommand}} and {{KW|DEFINT|DEF}} statements if used.
|
|
* Parameters can be defined in a DECLARE statement [[AS]] [[INTEGER]], [[SINGLE]], [[DOUBLE]], [[LONG]], [[STRING]] or [[ANY]].
|
|
* The Qbasic IDE can automatically DECLARE a SUB or FUNCTION once the procedure is called and the module is Saved.
|
|
* If a procedure is never called, it will not be automatically be DECLAREd by the Qbasic IDE when the program is saved.
