Comparison Instructions Section 3-6
Using CMPL(060) Results in the Program
Do not program another instruction between CMPL(060) and the instruction
controlled by the Arithmetic Flag because the other instruction might change
the status of the Arithmetic Flag. In this case, the results of instruction B might
change the results of CMPL(060).

Precautions Do not program another instruction between CMPL(060) and an input condi-
tion that accesses the result of CMPL(060) because the other instruction
might change the status of the Arithmetic Flags.
