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.

|
|
* Any string expression returns the size, in bytes, of free string storage space.
|
|
* Also compacts the free string storage to a single block of memory.
|
|
* 0 returns the same value as using a string expression above.
|
|
* -1 returns the size of the largest non-string array in bytes that could be dimensioned.
|
|
* -2 returns the amount of stack space, in bytes, available to a running program.
|
|
* Any other numerical value returns the size of the next block of string memory storage space.
