Re: Using sort sub as regular sub

fails to return anything.

Not even "undef" ?

Are you setting $a and $b before calling the sub ?

Please show your calling sequence.

I hope life isn't a big joke, because I don't get it.

Yes, I was setting $a and $b. I dumped the result into a string, which was blank, so I assumed the sub was sending back undefined. However, I went back to check for sure, ended up qualifying the call with its package name, and viola it immediately started working. So thanks for the question. :-)	[reply]
