Hi Geeta,
From my point of view, the first and foremost thing that should be looked into to tune the performance of the program is 'Looking at the database access statements'..

Possibly relacing the complex FIND statements with READ statements....

And may be (I am not very sure), the numeric data definitions can be considered............

I would appreciate if someone correct me if I am wrong....


Thanks

At least half of Natural's statements have performance considerations. So, the first thing you have to do is learn these.

Then, you have to learn how Adabas works, and how Natural interacts with Adabas.

The you should learn the use of SETTIME.....*TIMD

and hope he only picks statements that you have used?

Steve's comments almost sounded like RTFM.

For example:

READ, FIND, HISTOGRAM, READ WORK FILE, WRITE WORK FILE, GET

All arithmetic statements, ADD, SUBTRACT, MULTIPLY, DIVIDE, COMPUTE

CALLNAT, PERFORM, FETCH, FETCH RETURN

COMPRESS, SEPARATE, EXAMINE

DECIDE FOR, DECIDE ON, IF

FOR, REPEAT

MOVE, MOVE BY NAME, MOVE BY POSITION

REDUCE, EXPAND, RESIZE

SORT , SORTED BY clause of FIND


And I am sure I have skipped a few.
