Rather than write the IF statement with AND NOT I’ve just written separate IF
statements… first, check the field for the “.” first… then in a separate “if”
statement check the rest of your math… that seems pretty easy for a novice to
understand. It also provided a way to show that when the if statement wasn’t
met, nothing happened…
I’d even write it like this:
if char -1 of field "display" = "." then
delete char -1 of field "display"
else
-- do nothing
end if
be well,
