When the execution condition is OFF, CPS(026) is not executed. When the ex-
ecution condition is ON, CPS(026) compares constants and/or the contents of
specified words as signed 16-bit binary data and changes the status of compari-
son flags according to the results.
After CPS(026) execution, the A50005 (GR), A50006 (EQ), and A50007 (LE)
Flags will turn ON and OFF as shown in the following table.
