in reply to
perl beginner question
you have to use use modulename inside your .pl file.
if the .pm file is in the other directory, mention that path in the @INC variable, or use 'use lib' pragma, or -I option to the interpreter.
you can call that routine like classname::routinename as plain
with OO you can call classname->routinename
see my earlier post Re^3: A Class inside a Perl script?
