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 '''_MAPUNICODE''' function returns the [[Unicode]](UTF32) code point value of a mapped [[ASCII]] character code.
|
|
|
|
|
|
|
|
{{PageSyntax}}
|
|
:: UTFvalue& = _MAPUNICODE(Ascii_code%)
|
|
|
|
|
|
* The UTF32 values have 4 byte encoding so the return variable should be [[LONG]].
|
|
* The ''Ascii_code'' can be any [[INTEGER]] value from 0 to 255.
|
|
* Returns can be used to verify or catalog the present Unicode mapping.
|
|
* The function will return Unicode values for the control characters, CHR$(127) and extended characters '''without mapping''' them first.
|
|
|
|
|
|
''Example:'' Store function return values in an array for ASCII codes 0 to 255 to restore them later.
