Never mind, after writing up the email I noticed the csv_eol tag &
tried setting it to "\n" for grins, and it solved my problem.

Subject: Problems using the DBI class to access CSV files.
I've been using the DBI class for a while now & I'm trying to port some
code from a Windows environment where it is working perfectly to a Unix
environment where it's not really working. I've also reviewed the Perl
DBI book again & see nothing about this type of problem. It seems that
it's just the CSV type of database that is having issues.
I'm trying to parse pipe separated log files to search for data so that
actions can be taken based on what I find in the log files.
A sample log file:
TIME|Status|Description|
17:15:51|OK|No Problems|
17:31:12|Warning|Skipped file abc|
18:45:03|ERROR|Can't read file xyz|
Afraid that it might be a bug in my code, I began using "dbish" to test
out my queries. But I get the same problems as in my code. I find all
3 rows in Windows, but I always find Zero rows on the Unix platforms.
On Windows:
M:\...\logs>dbish
DBI::Shell 11.91 using DBI 1.49

'18:45:03','ERROR','Can't read file xyz',''
[3 rows of 4 fields returned]

But if I attempt to do the same thing against AIX Unix, I get

Can anyone offer suggestions?
