Use of uninitialized value errors

Hi All,

Thanks for the help so far!

I'm trying to figure out how to eliminate the uninitialized value errors in my perl code.

When doing the file split:

Code:

# Split Filename From Extention
  my ($base, $ext) = split (/\./, $argFileName);
# Check For File Extension
  $HaveExt = ( ( length $ext ) < 1 ? "Y" : "N" );

I get the following error:
"Use of uninitialized value in length at test.pl line 22.

For some items I may have 2 files that have the same name one with an extention and one without so I'm checking for the extention and using that later to filter the files.

I've tried a bunch of ways to get around this but I always get some form of uninitialized value error.

How can I intialize an uninitialized value?
I've even tried:

Code:

  $ext = "" . $ext;

but that also gets the error.

Thanks, in advance!
