Thanks for the advice, I certainly will do that (I hope to get to it later today). I'm not really sure how to run perl in the debugger. I apologize for not including the output or being more explicit in my original post.

The output is:

c:\WINDOWS>snp500eps xxx xxx scg@mailhost.com
Getting SNP file from web. . .
Done getting file. . .
Opened Spread...
19.24   18.52   18.13   16.97   17.24   16.31
68.65
Different values!
DB:     68.07
silly program doesn't know it's over at C:\Perl\bin\snp500eps.pl line 
+63.
WEB:    68.65
[download]

where it just hangs with a blinking cursor at the end of "68.65_" (the underscore is the cursor). It does get the spreadsheet, the spreadsheet can be opened and the values get printed out appropriately, and the email is sent (so I know the variables' values are fine, and it certainly appear that it does actually get to the die function).

Typically, I do use warnings, one reason I didn't here is because I notice a warning coming out of BasicRead related to a pack statement (this doesn't seem to interfere with actually reading the spreadsheet, however).
