in reply to perl eval
Would your code work without the eval?
Hint:
sub egal ()
does not do what you want, or, maybe in this case, actually does what you intended at one time.
Consider this program:
#!perl -w use strict; my $param = shift; print "About to run: [$param]\n"; my @res = eval($param); print $@ if $@; sub egal () { print "Got arguments [@_]\n"; }
Also, consider running your programs using perl -w. That way, Perl will tell you about things that might not be what you think them to be. Especially, there are no true or false keywords in Perl.
