Re: Re: Matching a KEY in a HASH

I must not be making myself clear...

The $variable = "" could = Anim or CAD or anything in the list...

My question is ... How do I search the HASH to match the $variable, but print the VALUE only...

make sense?

I must not be making myself clear. The point of a hash is that a hash itself can find a value for a given key trivially. `$value_you_are_looking_for = $category{$variable};` [download] There's no searching required. If there's an element with a key of `$variable`, then `$value_you_are_looking_for` has it. Otherwise, it gets `undef`. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]
