IF...THEN... statement and logic expression

jj02148 — Mon, 22 Aug 2016 16:52:27 GMT

Hi All,

I ran into a problem in which I need to write a long logic expression: A01=1 OR A02=1 OR A03=1 OR A04=1 OR... A15=1 then TF=1;

Not sure if there is an easy and quick way to write the code? Say, IF any of (A01--A15) =1 then TF=1?

Thanks

If you create an array holding the variables, there are two methods. The array:

array alist {15} a01-a15;

Then you could search with:

if whichn(1, of alist{*}) then TF=1;

Surprisingly, this method also works (once the array is defined):

if 1 in alist then TF=1;
