I am a Perl rookies that seek you wisdom. I am working on a project and I need to parse around some variables to separate modules I have created.
use var qw($readMode $writeMode $appendMode);
$readMode = '';
$writeMode = '>';
$appendmode = '>>';
my $mode = pop(@_)
open(FILENAME, $mode, EXPR);
I have multiply mudules that I will like to use the various file modes that I have define in this module say called "moduleA". In moduleB that is locate in a separate file, I use the following code;
Whenever I run the code, I see the following error
"Global symbol "$readMode" requires explicit package name at ..."
Could any Monk kindly fill me with wisdom? note, I don't want to $readMode by way of a subroutine.
