In the server procedure sometimes the Read generates an extra predicate (which
has not been coded as part of the read statement). Hence the index is not used
even if one exists.
Best Practice:
Each Read is coded in open action block each. They are often called the
Read Action Blocks (RAB). COOL:Gen generates the extra predicate whenever it is
not sure whether the read is for an update or just a read only.

We offer (arguably) the best, most cost-effective, most automated CA-GEN and traditional Mainframe re-engineering solution in the industry.
Our automated parsing tool aka Vintool directly works on CA-GEN text output and converts to directly executable and (most importantly) readable Java application.
We also have a comprehensive suite to migrate Mainframe/COBOL to open systems.
I would like to invite you (and IT leadership) for a brief 15 minute online presentation on the
capabilities of our solution.
Also attached are a sample code and screen shots.

Please provide your feedback either way. Appreciate your time
