but if FIELD B is empty, I want to have just
I can easily do it in two script steps - set my result as FIELD A, then test for FIELD B and add a comma followed by field value if not empty, but can I do something like this to get it into a single script step?
$var = Value (FIELD A) & (IF (FIELD B): ", " & FIELD B; "")
(probably don't even need the semi-colon and final "", but you get the idea).
