7.1 Replace instructions with different QCPU instruction format (excluding AnACPU/AnUCPU dedicated instructions)
(2) Occupied device points
The "ASC" instruction in ACPU occupies 4 words. The number of device points occupied by the "$MOV"
instruction in QCPU may change according to the number of characters+1 byte.
When replacing an "ASC" instruction that specifies 8 characters with the "$MOV" instruction in QCPU, the
number of occupied points increases because the stored ASCII code occupies 4 devices + 1 word (delimiter
"00H"). If the additional device was being used for other purposes, its content will clear to "0000H".
Modification is necessary when the devices used by the "ASC" instruction +1 are used for other operations.
