EQU(025)
When the execution condition is OFF, EQU(025) is not executed. When the ex-
ecution condition is ON, EQU(025) compares the content of Cp
1
to the content of
Cp
2
and creates an ON execution condition if the two values are equal or it
creates an OFF execution condition if they are not equal.
EQU(025) is an intermediate instruction, like NOT(010), CMP(020), and
CMPL(021). Intermediate instructions are entered between conditions or be-
tween a condition and a right-hand instruction. Intermediate instructions cannot
be placed at the end of an instruction line.
The up-differentiated version of EQU(025) behaves like the undifferentiated ver-
sion when Cp
1
is equal to Cp
2
and will turn OFF for one scan only when Cp
1
is
not equal to Cp
2
.
