Calculation with variables
Variables are calculated every time you exit an input/output field (by pressing the ENTER or
TOGGLE key). The calculation is configured in a CHANGE method that is processed every
time the value changes.
You can scan the variable status to ascertain the validity of the value of the variable, e.g.,
Var1 = Var5 + SIN(Var2)
Otto = PI * Var4
Addressing system variables indirectly
A system variable can also be addressed indirectly, i.e., as a function of another variable:
PRESS(HS1)
AXIS=AXIS+1
WEG.VAR="$AA_DTBW["<<AXIS<<"]"
variable
END_PRESS
