Subject: Breaking large files into smaller ones
> Hi there,
> I have a large file generated from my legacy system which I want o break
down into smaller one before being passed to my SAP system... does anyone
have any sample code that I can use? I'm after a logic that counts the
number of lines, and ever 200 lines it creates a smaller file.
