in reply to problem with accessing PM file

This is a problem of scope.

When you declare my $s_month; you are scoping the variable to your main program.

You need to get the value from $schedule::s_month, and you do not need to re-declare this in your main program at all:

require schedule;

print "\$smonth is $schedule::s_month ,\$sday is $schedule::s_day, \$s
+year is $schedule::s_year\n";

Your other option is to write a proper perl module that exports $s_month into the main program namespace. Be warned though, if you do this you will still clobber that value if you declare my $s_month in your main program.

Check out perldoc perlmod for more information on writing a module.

Updated: I needed to brush up on my vs. main::. Thanks for pointing that out, Zed.

    Lexically scoped variables are separate from package variables, including those in the default package of main. 
    $x = 2;
my $x = 3;
print $main::x, ' ', $x, "\n";
$main::x = 4;
print $main::x, ' ', $x, "\n";
