How do I stop warnings from external packages? Justin C 03-11-2008

 I have a program with a 'require' line. The required item is another
program which puts a whole bunch of stock codes from an SQL database
into a hash, the has is what is used in the main program. I'm not
familiar with working this way (I have no idea how I wrote that in the
first place!).

The require is something like this:

package ProductCodes;
%codes {
.
.
.
}

within the main program I have a line which generates a warning, the
line:

print $ProductCodes::codes;

The warning is:

Name "ProductCodes::codes" used only once: possible typo at

How can I stop this without turning off warnings?

Thank you for your suggestions.

        Justin.

Replace require by use or

{ no warnings 'once'; print $ProductCodes::codes; }
