Re: %Trim dilemma






Ron, I feel your pain, but it's the only correct way to evaluate that 
statement.

I think where you are getting tripped up is that you 'think' you're
comparing stupidfield to a string of 9s.   You are not comparing
stupidfield to a string of 9s.

You are comparing the bif %trim() to the special value *all'9'

*all'9' has it's own quirks, which have not changed since the
beginning (at least RPGii).   %trim() has it's own rules which have
not changed since it's inception as well.
