I'm not quite sure what you're asking for so I'm going to try and
rephrase your question, then answer that one. :-)
Question: I have a key in my hash that could have several valid
values. For instance, $hash{key} could return "foo" and "bar" and
my program would be ok with that. What is the best way to figure
out what value $hash{key} has?
I hope that I got the question sorted out right in my head. The
answer I would give to that question is, use an if statement:
if ( $hash{key} eq 'foo' ) {
# do stuff based on 'foo' here
} elsif ( $hash{key} eq 'bar' ) {
# do stuff based on 'bar' here
} else {
# we should probably throw an error here because there are no
# valid values of $hash{key} left
}
If I got this wrong, and it's very possible, try and set me straight
so we ( the list ) can help you better.
Thanks,
Casey West
