This is because I haven't written the code but it is part of a module that other people have reported be work for them. I have posted it. To me the 1.000.000 USD question would be: Is there any way to debug this? Like for example print a list of all known subs at a given point in time?

There's nothing in the snippet you posted to explain the error; it should be working. Is this a pure CGI environment, or are you running under mod_perl or similar? Are you sure there is no package statement before the declaration of usedLater? Are you positive there are no typos? -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
