When the execution condition is OFF, ZCPL(––) is not executed. When the
execution 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.

CD , CD+1< LL+1,LL

0

0

1

LL+1,LL 

≤

 CD, CD+1 

≤

 UL+1,UL

0

1

0

UL+1,UL < CD, CD+1

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.

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.

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.

Cp1: First compare word

IR, SR, AR, DM, HR, TC, LR, #

Cp2: Second compare word

IR, SR, AR, DM, HR, TC, LR, #

Third operand: Set to 000.

When the execution condition is OFF, CPS(––) is not executed. When the
execution condition is ON, CPS(––) compares the 16-bit (4-digit) signed binary
contents in Cp1 and Cp2 and outputs the result to the GR, EQ, and LE flags in the
SR area.

1. Refer to page 27 for details on 16-bit signed binary data.

2. Refer to 5-17-2 Compare – CMP(20) for details on saving comparison re-

sults.

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.
