Re: How do I avoid a die generated by a module?

The block version of eval should do it e.g

eval {
  die "let's blow this joint!";
};
warn "ack - $@" if $@;

__output__

ack - let's blow this joint! at - line 2.

That did it--not sure how I missed the block version of eval, but thank you very much for your help!! Now I just have to figure out where my understanding has gone wrong regarding my attempt to catch the DIE signal and handle it myself completely (i.e. do what I want with the error, including not dying if so I choose).

You can't catch and prevent a death using `$SIG{__DIE__}`. You have to use eval, as broquaint said. Once you've got the code that dies wrapped in an eval, all you need to do to "catch the DIE signal" is run the eval block, and then test to see if `$@` is set, afterwards (as broquaint's code does with the warn). If it's set, then something in the eval block died. There's no way to prevent the code in the eval block from halting from the death. You just have to recover outside the block and then restart it, as needed. If you've ever used a language with exceptions (eg, Java), it's more like a try / catch pair, then catching and ignoring signals. Hope that makes it a little more clear. bbfu Black flowers blossom Fearless on my breath	[reply] [d/l] [select]
