MEM Reserve Memory

The operand for this directive is two absolute addresses, separated by a comma. The absolute addresses specify a range of memory that is to be reserved as a data area. The link editor will insure that subroutines are not placed in this range of memory. This is done by checking the length of each subroutine to see if it will enter a reserved area. If it does, it is started after the end of the reserved area. This directive is intended for use when the high resolution graphics pages are needed.
