Function
ZCP
ZCP(088) compares the 16-bit signed binary data in CD with the range defined by LL and UL and
outputs the result to the Greater Than, Equals, and Less Than Flags in the Auxiliary Area. (The Less
Than or Equal, Greater Than or Equal, and Not Equal Flags are left unchanged.)
When S > T2 as shown below, the > flag turns ON.
When T1 S T2, the = flag turns ON. When S < T1, the < flag turns ON.
ZCP(088)Result
CD > UL
CD = UL
LL < CD < UL
CD = LL
CD < LL
ZCPL
ZCPL(116) compares the 32-bit signed binary data in CD+1, CD with the range defined by LL+1, LL
and UL+1, UL and outputs the result to the Greater Than, Equals, and Less Than Flags in the Auxiliary
Area. (The Less Than or Equal, Greater Than or Equal, and Not Equal Flags are left unchanged.)
When S+1,S > T2+1,T2 as shown below, the > flag turns ON.
When T1+1,T1
When S+1, S < T1+1, T1, the < flag turns ON.
ZCPL(116)Result
CD+1, CD > UL+1, UL
CD+1, CD = UL+1, UL
LL+1, LL < CD+1, CD <
UL+1, UL
CD+1, CD = LL+1, LL
CD+1, CD < LL+1, LL
