in reply to Hash Uninitialized Values Error

FWIW, the DECISION heredoc wasn't printing out. I believe that it has something to do with heredocs needing to be flush with the left margin. As a quick workaround, I used Filter::Indent::HereDoc. Here's a simplified example:

#!/usr/bin/perl use strict; use warnings; use Filter::Indent::HereDoc; DECISION: { { print <<EOF; Hi. This is the Lee-Hardy Conclusion Calculator. Given a series of statements using the syntax 'p -> q', I will deduce the correct conclusion to be made using basic logic and the chain rule. Type 'ready' when you are ready to input your statements. Type 'quit' to exit the LHCC. EOF } }

    DECISION: is a statement label. There are multiple places where goto is used to go to the label. Misguided programming style I know, but allowed.

    There is no DECISION heredoc, the OP doesn't need a source filter to solve a nonexistent problem
      It would not print on my system. There is a problem there. You're full of it.

        It would not print on my system. There is a problem there. You're full of it.

        Like the OP says, the code as posted doesn't call the subroutiine, so of course it won't print anything

        Also, the code contains no heredocs of any kind, the OP is merrily using quotes to successfully print the text he wants to print

        so misidentifying a loop label as heredocs, then telling the OP to switch to a source filter for heredocs, is just more of the same non responsive nonsense trolling by you Khen1950fx ...

        Nothing probably prints because it's a subroutine. I have a .pl file that calls Unit3::LHCC because it's in a file called That's not the problem.
