Dear Monks, I've a problem using quotes in a self reference scenario. The situation in my script is, that, if you want to insert the code from sub b and sub c into sub a (between quotes), you will get some props to keep to code printed out looking absolutely equal to the code listed above. Please can show me someone a proper solution, where this condition halts. Or a solution, so that the script above prints its code with single parenthesis around it. Thanks a lot in advance. nighthawk_

#!usr/bin/perl

# Just insert the code from sub b and sub c in sub a where the tree do
+ts are.
sub a {    my $input = shift; return 'sub b{...}; sub c(...)'; }
sub b { my $input = shift; return 'sub a { my $input = shift; return \
+''.$input.'\';}'.$input.';';}
sub c { my $input = shift; print $input.'print &c(&b(&a()));';}
print &c(&b(&a()));
