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|HEX$}} function returns the base 16 hexadecimal representation of an [[INTEGER]], [[LONG]] or [[_INTEGER64]] value as a [[STRING]].

:''result$'' = {{KW|HEX$}}({{Parameter|decimal_number%}})

{{PageDescription}}
|
|
* The function returns the string hexadecimal (base-16) representation of a ''decimal'' integer.
|
|
* If the parameter is not an Integer, it will be converted to one by HEX$.
|
|
* The function does not return a leading sign space so [[LTRIM$]] is not necessary.
|
|
* Can be used in place of [[STR$]] to trim both sides of positive decimal values 0 to 9 only.
|
|
* [[VAL]] can convert the string value back to a decimal value by prefixing the string return with "&H".
