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 '''&O''' prefix denotes that a integer value is expressed in an Octal base 8 format.

|
* The base eight numbering system only uses octal digit values of 0 to 7.
|
|
* Leading zero values '''can''' be omitted as they add nothing to the return value.
|
|
* Decimal values returned can be any '''signed''' [[INTEGER]], [[LONG]] integer, or [[_INTEGER64]] value so use those type of variables when converting directly as shown above. The program [[ERROR Codes|"overflow"]] error limits are listed as:
|
|
:: * [[INTEGER]]: 6 octal digits or a decimal value range from -32,768 to 32,767
|
|
:: * [[LONG]]: 11 octal digits or a decimal value range from -2,147,483,648 to 2,147,483,647
|
|
:: * [[_INTEGER64]]: 22 octal digits or decimal values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
|
|
* [[LONG]] Octal values can be expressed by appending & after the number. Example: &O100000& = 32768

''Example:'' The maximum octal values of decimal value -1 in each numerical type are:
