RE: RPG/SDA Question

[Peter Trahan <peter.trahan@xxxxxxxxxxx>]

Here's an Update on SFLNXTCHG.  I found in the DDS manual (rather than the
SDA Manual) a more detail explaination of the SFLNXTCHG keyword.  It seems
that it is only in effect (indicator or not) after a record is changed, an
error is found and the SFL is read again.  The records in error or
read(READC) even though the user didn't change them.  Hence the records will
always return an error until they are corrected.  In other words the record
has to have been originally modified by the user.  
THANKS AGAIN!   Peter

The problem I've had with READC is that if any IO happens, the modified data
tags get reset...and...on most any subfile application that actually does
anything, some kind of IO happens between the change and the readc.  I don't
use readc much anymore because of this........just my opinion.
