I can't find an exit in your code snippet. Assuming you run through the entire code, and leave it with the last line shown, it's obvious it returns 0 as the last echo succeeds.

If you ask yourself why your finds always output a success, look at the RETVAL variable: it's set by the exit code of an obscure command run before the entry into your code snippet.

Where can I find a list of exit codes? (Exit code 64)

I'm receiving an exit code 64 in our batch scheduler (BMC product control-m) executing a PERL script on UX-HP. Can you tell me where I can find a list of exit codes and their meaning. I'm assuming the exit code is from the Unix operating system not PERL. (3 Replies)

Test::Synopsis(3pm)					User Contributed Perl Documentation				       Test::Synopsis(3pm)

NAME
Test::Synopsis - Test your SYNOPSIS code SYNOPSIS
# xt/synopsis.t (with Module::Install::AuthorTests) use Test::Synopsis; all_synopsis_ok(); # Or, run safe without Test::Synopsis use Test::More; eval "use Test::Synopsis"; plan skip_all => "Test::Synopsis required for testing" if $@; all_synopsis_ok(); DESCRIPTION
Test::Synopsis is an (author) test module to find .pm or .pod files under your lib directory and then make sure the example snippet code in your SYNOPSIS section passes the perl compile check. Note that this module only checks the perl syntax (by wrapping the code with "sub") and doesn't actually run the code. Suppose you have the following POD in your module. =head1 NAME Awesome::Template - My awesome template =head1 SYNOPSIS use Awesome::Template; my $template = Awesome::Template->new; $tempalte->render("template.at"); =head1 DESCRIPTION An user of your module would try copy-paste this synopsis code and find that this code doesn't compile because there's a typo in your variable name $tempalte. Test::Synopsis will catch that error before you ship it. VARIABLE DECLARATIONS
Sometimes you might want to put some undeclared variables in your synopsis, like: =head1 SYNOPSIS use Data::Dumper::Names; print Dumper($scalar, @array, \%hash); This assumes these variables like $scalar are defined elsewhere in module user's code, but Test::Synopsis, by default, will complain that these variables are not declared: Global symbol "$scalar" requires explicit package name at ... In this case, you can add the following POD sequence elsewhere in your POD: =for test_synopsis no strict 'vars' Or more explicitly, =for test_synopsis my($scalar, @array, %hash); Test::Synopsis will find these "=for" blocks and these statements are prepended before your SYNOPSIS code when being evaluated, so those variable name errors will go away, without adding unnecessary bits in SYNOPSIS which might confuse users.
