in reply to How to use variables from other package?

Lexical variables (those created with my) do not show up in the symbol table, and thus can't be accessed via the $Packagename::variable syntax. In this case (assuming perl 5.6.0 or later), you'll want to do:

package CNLLog; our $_POST_CONVERSION = "postConversion"; our $_CORRECTIVE_SCRIPTS = "correctiveScripts";

..and in the other file..

print $CNLLog::_POST_CONVERSION;

Older versions of perl will need to use the use vars pragma. See perldoc vars.

Update: One should also mention the wonderful article Coping with Scoping, by MJD. See also 'our' is not 'my'.

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'
