RE: Eval with two equals?

["Joel Fritz" <JFritz@xxxxxxxxxxxxxxxx>]

That's why it's convenient to have an assignment operator and a
comparison operator.  If RPG supported something like
logical_var = (x == 10);  there'd be no confusion. 

Seems to me I tried assignment on the right side of an equals sign a few
years ago and it didn't work.  Personally, I never liked doing that in a
language that supported it.  There are a lot of cases where a more
verbose way of doing something results in the same machine code as the
terse version. 

Because I work in a shop where a lot of people use IFEQ et. al. I like
to use things like logical_var = (x = 10) out of perversity.  If they
can use left hand indicators and avoid using select, I can use my own
forms of obfuscation.
