perldoc -f do Specifically the section for 'do EXPR' and more specifically the example at the bottom. You should be error checking your call to 'do'. And of particular importance is the line: "Note that inclusion of library modules is better done with the "use" and "require" operators, which also do automatic error checking and raise an exception if there's a problem." In this case you need to provide the package name for $v because it hasn't been declared, or declare it with 'our'. perldoc -f our Either in 'main.pl', add: our $v; or use, print "value of v is $::v\n"; Of course there are better ways to handle program configuration, there are numerous modules on CPAN for handling all manners of formatted config files. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
