If you go and get that, that might give you an idea of how to interface with an mail transfer agent like sendmail. Yes that's right: rather than battle with the vagaries of whichever user agent you care to use, the easiest thing is to put recipients and subjects straight as email header and pass the whole thing from the standard input to the transfer agent. In your case, it might be something as easy as running /usr/lib/sendmail -t <<! To: somebody Subject: whatever thought you might be interested to know.... ! Which you would collate under 4gl. Also, you don't really need to battle with assembling weird command lines in 4gl and passing them to the RUN command. If you go to the IIUG software repository and get fglio, you can open pipes straight from 4gl and read/write text straight from/to them. -- Ciao, Marco ______________________________________________________________________________ Marco Greco /UK /IBM Standard disclaimers apply!
