Remarks
POKE provides the functionality of a dynamic pointer: the datatype parameter specifies the data type and also the size of the target data to write to the target memory address.
Datatype can be any one of BYTE, WORD, DWORD, INTEGER, LONG, QUAD, SINGLE, DOUBLE, EXT, CUR.
It is the programmer’s responsibility to ensure that POKE does not overrun the target memory area to avoid data corruption or protection faults.
