Re: Undefined subroutine - newbie problem

An “extreme fast Perl workshop?”   (blink...)

“Ordered to” finish a few programs ... “For a positive grade?”   What is this, high school?

No, it’s probably the beginnings of what we call a “death march,” only sugar-coated and draped in quasi-athletic jerseys.   In the real world, you don’t get brownie points for doing work “quickly.”   Your work will be in production for a dozen years so it must be done well.   If the company is pressuring you to learn how to sling-out garbage “quickly,” then very quietly but very quickly look for another job.   One that provides professional training but without the jock-strap expectations and misguided pressures.   If you survive in such a place for more than a year (and they probably calculate that only a small percentage of you actually will ...), then you will be doomed to maintain that code.

“It takes three times as long to do it wrong.”   If you are in a situation that emphasizes “speed,” either so that you “do not fail” or in order to prove what a whatever-you-think-you-are you are, instead of teaching you how to produce real quality, then you are in a lose-lose situation that they write books about.   It takes time to learn how to do this well.   Make sure that they are guiding you toward realistic and sustainable expectations.

well probably you much misunderstood me; it is just Perl basics training and much of the exc is done by me, was quite easy for me and after classes and manual reading wasn't problematic for me; but there are higher graded solutions and my goal is to finish them, but I found that problem on my way and I need help.

Help you will certainly find here in abundance.   Your problem is a missing use statement, methinks.   In one module you must say what is exported; in its clients, you must tell Perl to use it.

There are wretched situations out there just like the one I described, especially for “captive audiences” in foreign countries on work-visas.   I feared that you had become caught in one...   The word, “extreme™” has become to me a bellwether of abusive practices.   If false alarm, great.
