Re: Getting brackets right, checking for package subs

It would help us to help you better if you told us, exactly what errors you get in which case.

Personally, I always use the following snippet to handle symbolic references:

no strict 'refs';
defined &{ "$package\::$subname" }

but as I see that you're using a variable named $runmode, I get the feeling that you'd be better served by a simple dispatch table, especially as that brings you some more security:

my %runmodes = (
    init => \&init,
    login => \&login,
    ...
);

Ahh brilliant. Thanks. I've adapted this a little and ended up with:- `defined &{ "${package}::$rmhash{$runmode}" }` [download] Which works with strict ref turned on. I would use a dispatch table, but that runmode hash is from CGI::Application. Lyle	[reply] [d/l]
