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 '''_MEMPUT''' statement writes data to a portion of a designated memory block at an OFFSET position.

::: '''_MEMPUT ''memory_block'', ''memory_block.OFFSET''''' [+ ''bytes'']''', ''source_variable''''' [AS ''type'']
|
|
|
|
|
|
|
|
* ''memory block'' is a [[_MEM]] variable type name.
|
|
* ''memory block.OFFSET'' is the dot [[OFFSET]] byte zero memory position where block data begins.
|
|
* The ''source variable'' designates the size and place it will be read from. It can be a variable, array or user defined type.
|
|
* The ''source variable'' is converted to a specific variable ''[[TYPE|type]]'' before it is copied to the ''memory block offset'' as bytes.
|
|
|
|
|
|
''Example:'' _MEMPUT can be used just like [[POKE]] without [[DEF SEG]].
