[MacPerl] MacPerl: Attempting read of folder of files

[WagsWorld <WagsWorld@aol.com>]

I am running MacPerl 5.1.9r4 and am attempting to read a number of e-mail
files of which I want to extract the return path so as to block junk mail.
Unfortunately most of my work is done daily on NT 4.0 and MKSToolkit 6.1 using
perl. The script I have I believe would work on it, but I keep getting
following error:

# WagsWorld 2 :Applications:MacPerl  :00 Macperl  :PL001: Unable to open
aaaa , <STDIN> chunk 1.
File 'WagsWorld 2 :Applications:MacPerl  :00 Macperl  :PL001'; Line 44

It is probably something very simple I am missing, but any help would be
greatly appreciated.  I get the chdir to print that it was successful.

Thanks.
