RE: Update the subfile record using Readc

Use READC to read through all subfile records which have had their
contents changed. Check the contents (filling in blank will also cause
the readc to read that record). While in the loop of readc-ing: keep
track of the rrn of the first record with a selection. If you find
another record with readc which has a selection: seton the error-flag
and update that record. Once you finished the readc-loop, go back to the
first selected record with chain and error-flag that one as well (since
either record may be in error)..

So the answer is that you may very well need both readc and chain.

Also mind the remarks of the other reactions, they made very valid
points.

Subject: Update the subfile record using Readc


Hi,

I have a subfile which looks similar to the one below.

Select X

Opt Product
_ ABC
_ XYZ
_ LMN

Now if i select two records i need to update the subfile with
the error message and reverse image on as only one selection
is allowed.

I can do this by chaining the subfile with the RRN, but can i
do the same by using readc?
Do i have to use any other keyword for this. How do i update
the subfile(how do i chain it to the record to be
updated/reverse imaged on the subfile using readc)


Thanks in advance

Derek
