Mark,

I came to that realization yesterday afternoon. Special file processing isn't the right tool. When I started this experiment I didn't realize it only handled sequential I/O.

I thought about using triggers but haven't had a chance to explore it yet.

Hi, Rick:

Perhaps a SPECIAL file is not the right tool for the job? Others have
mentioned in the past that SPECIAL files were supposedly designed to only support the model of a "sequential" file, not a keyed file, using CHAIN, etc. :-o

Suppose you create an empty version of the file in question, and attach insert, delete and update triggers to that copy of the file... then, your existing program can continue to write, update or delete to a "real" file that has exactly the same record formats, layouts., etc., and the trigger programs can take care of splitting up the various data fields into one or more alternate files.

Is this not one of the scenarios that triggers were designed for?

All the best,

Mark S. Waterbury
