- STACK2_INC = -1 ;[3] remember file has been included
- FAT_COW = 300h ;[6] Extra slop just in case
- STACK_SIZE = 0800h + FAT_COW ;[3] Default stack size (MUST BE EVEN)
- STACK_MIN = 0320h + FAT_COW ;[3] Minimum stack size
- STACK_CHECK = STACK_MIN-20h+1h ;[3] Stack check marker offset (MUST BE ODD)
