in reply to Understanding using external program data

You should make a module and "use" it. Here's an example:
#!/usr/bin/perl use strict; use warnings; use Lookup; use Data::Dumper; print Dumper \%devel_table;
And then the module (I usually capitalize modules):
package Lookup; use strict; use warnings; require Exporter; our @EXPORT = qw(%devel_table); our @ISA = qw(Exporter); our %devel_table = ("Townhomes West" => "M", #lots more values in here, of course "Winding Creek Family" => "H", "Dayton Lane Gardens" => "H"); 1;

    So, in the module, you Don't use the #! line-- you say "package <packagename>;". Such a simple thing, but I just couldn't see it. Everything works now. Thanks!
      Oh dear, that's a very superficial description of the situation.

      The "hashbang" line in a script and a "package" line in a module have very little in common. One is Perl, the other isn't, for one essential difference. Each can usefully appear in the other kind of file, so they're not even distinctive.

      Please read up on the function of each. See perldoc perlrun for the hashbang line and perldoc perlmod (plus perldoc -f package for the package statement.
