With all this talk about converting Clipper for use on a network ... I would like to know how I can make Clipper perform TTS (Transaction Tracking)? In other words, roll-back a transactions (ie. REPLACE ALL FIELD WITH 0) when the workstation that issued the command reboots in the middle of the REPLACE. Also, if TTS is available on Clipper; can I turn on a transaction and turn it off. In other words, turn on TTS ... perform several commands ... and turn off TTS; making all the "several commands" look like a single transaction. Thanks in advance for all replies. __________ Carnegie Mellon University ___ / \ / / /_/ / /\/ _/ / / / "Happy Computing ..." __/. /__ / / / / / / / / -- Computer Dr. / / Internet: Johnny.J.Chin@andrew.cmu.edu / ------- / 4730 Centre Ave. #412 BITnet: jc58@andrew \__________/ Pittsburgh, PA 15213 UUCP: ...!uunet!andrew.cmu.edu!jc58

You cannot, in the sense that Clipper itself would rollback an aborted transaction. You would have to manually program this type of feature into any software you develop, via a journal file or some other method. MD -- -- Michael P.

They support the Novell TTS stuff. tom
