 function block calculation module
VBScript Statements, VBScript Functions, Calculating fields, Visual Basic, Visual Basic Script
Hello,

I would like to know how to read this code and what the outcome would be. its writtin in a calculation function block which typically includes IF-THEN-ELSE, DO-WHILE, etc. statements.

out1 := (in2 = 0) ? 0 : ((in1 & in3) > 0);

of course in1/2/3 are the inputs, out1 is the output. Is this a type of IF-THEN-ELSE short-hand?

Thank you;

It seems likely to mean something like:
if (in2 = 0) then out1 = 0 else out1 = ((in1 & in3) > 0) ;

But it's hard to tell because you haven't told us what language it is written in.

I was able to play with the software. It is a simple ST (Structured Text) code. once I tested a few IO it was obvious that it is indeed an IF-THEN-ELSE structure, known as “?:” operator.
TomLiotta thanks for your reply. your presumption was correct.
