Perl Question

[Jeremy Russell]

I forgot the surrounding eval statement...the code was being dynamically
generated.

I would imagine that you either have an invalid declaration, invocation, or
something inhibiting a normally acceptable invocation such as use strict or
a scoping issue.

Proper declaration:
    $subref = sub { code_here };
Proper invocation:
    &$subref( args );
        or
    Package::&$subref;

After checking declaration/invocation syntax, I would comment out the use
strict, and see if it works. If it doesn't, I would check my scope--is the
sub declared in the correct package? Is it possible for the subroutine
reference variable to be out of scope?

Without seeing code, I can't see to help more.

Are you not able to duplicate the conditions which generated the code in the
first place? Blind code generation works in theory, but often *only* in
theory ;-)
