eval() is part of the standard distribution of PERL.

If you wanted to allow the program to keep running until the user exits you could use something like this:

#!/usr/bin/perl $| = 1; while( ) { print "Number, plz: "; $input = <>; chomp $input; print "\nOutput is: ", ( ($input*2)-1 ), "\n"; }
That seemed to work on my system.

If you make something idiot-proof, eventually someone will make a better idiot.
I am that better idiot.
