Precautions
Placing other instructions between ZCP(88) 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 is greater than UL.
EQ
:
ON if LL
≤
CD
≤
UL
LE
:
ON if CD < LL.
GR
:
ON if CD > UL.
The following example shows how to save the comparison result immediately. If
IR 100 > AB1F, IR 00200 is turned ON; if #0010
≤
IR 100
≤
AB1F, IR 00201 is
turned ON; if IR 100 < 0010, IR 00202 is turned ON.

Limitations
The 8-digit value in LL+1,LL must be less than or equal to UL+1,UL.
CD and CD+1 must be in the same data area, as must LL and LL+1, and UL and
UL+1.
