A BSMTP mail file can contain multiple emails separated by lines that consist of a single dot. I need to extract the individual emails into their own files. I wrote a pure Rexx filter to do it which works, but is excruciatingly slow for large inputs as it goes line by line through the input deciding whether to start a new output file or not and then append the line to the appropriate file (you know, peekto, look at the input line, check for the single dot, append it to the current file if not, else start a new file and write it there, readto, rinse, repeat. It concocts output filenames on-the-fly and writes them to the primary output (which I then dump into a stem for subsequent processing).
I clearly need a more PipeThink oriented approach. This is just too brute force. Any ideas? -- bc
