My perl program had some conditional statements that checked whether a

and I quickly realized it was treating pipes and zeros equivalently. To
make sure I was not going insane, I put the following checks:
if ( '1' == '|') { ... some statement ... }
if ( '0' == '|') { ... another statement ... }
By any sensible measure, both statements must return FALSE. First one
did that. Second one returned TRUE.
What's going on and how do I get around it?
My guess is that you do not want to do a numerical comparison.
Use 'eq' for a stringwise comparison.
