Re: Special file parameter issue

["Mark S. Waterbury" <mark.s.waterbury@xxxxxxxxxxxxx>]

 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

The issue I am having is that the parameters aren't changing between a write and a read operation.  I want to test the error handling if a read operation fails.  I can't get it to fail because the parms passed are the same ones I used to add a record even though I explicitly change them in the caller.  Any ideas?
