Like it or not, modules are the best way. Modules need not be
difficult; you probably need only a small fraction of the many
options available to a module author. To get started, see
tachyon's Simple Module Tutorial, including the other
monks' comments at the bottom. If the tutorial is too simple,
try perlman:perlmod. If too complex, try my skeleton code below.
I have pared it down to the bare essentials for illustration
only; it runs correctly, but is missing the seat-belts
(use strict) and air-bags (use warnings), so don't
take it out of the parking lot!
Use h2xs -n Common_Code -AX to generate a real
module template once you are more comfortable with how a
# this is in file Common_Code.pm
print "DEBUG: I see ", join(", ", @_), ".\n";
Here's a script which uses it:
my( $a1, $b2, $c3 ) = qw( red blue green );
Common_Code::log_debug_message( $a1, $b2, $c3 );
DEBUG: I see red, blue, green.
