Description
When the execution condition is OFF, ZCPL(––) is not executed. When the exe-
cution condition is ON, ZCPL(––) compares the 8-digit value in CD, CD+1 to the
range defined by lower limit LL+1,LL and upper limit UL+1,UL and outputs the
result to the GR, EQ, and LE flags in the SR area. The resulting flag status is
shown in the following table.

Precautions
Placing other instructions between ZCPL(––) and the operation which accesses
the EQ, LE, and GR flags may change the status of these flags. Be sure to ac-
cess them before the desired status is changed.
Flags
ER:
Indirectly addressed DM word is non-existent. (Content of
∗
DM word is
not BCD, or the DM area boundary has been exceeded.)
LL+1,LL is greater than UL+1,UL.
EQ:
ON if LL+1,LL
≤
CD, CD+1
≤
UL+1,UL
LE:
ON if CD, CD+1 < LL+1,LL.
GR:
ON if CD, CD+1 > UL+1,UL.
Example
Refer to 5-17-6 AREA RANGE COMPARE – ZCP(88) for an example. The only
difference between ZCP(88) and ZCPL(––) is the number of digits in the com-
parison data.

Description
When the execution condition is OFF, CPS(––) is not executed. When the exe-
cution condition is ON, CPS(––) compares the 16-bit (4-digit) signed binary con-
tents in Cp1 and Cp2 and outputs the result to the GR, EQ, and LE flags in the SR
area.
Note
1. Refer to page 29 for details on 16-bit signed binary data.
2. Refer to 5-17-2 Compare – CMP(20) for details on saving comparison re-
sults.
Precautions
Placing other instructions between CPS(––) and the operation which accesses
the EQ, LE, and GR flags may change the status of these flags. Be sure to ac-
cess them before the desired status is changed.
