RE: Performance Issue clearing Arrays

["Tanveer, Mohammad" <MTanveer@xxxxxxxxxxxxxxxx>]

I think my only question is that CLEARING ARRAYS in a program is a
performance issue or not specially in case of 9999 arrays all filled with
1000 bytes?

Sorry about the confusion, I am confused that's why I sent that message ;-)

Mohammad,

I'm not quite sure I understand your question exactly, but try this:

Instead of clearing the arrays or mult occur ds each time you call your
program, if you are filling the array/mods from top to bottom, try just
passing the occurance number of the last array/mods element used, along
with the data.  Then your calling program will not care if the rest of the
mods has been filled previously, it will only use the ones filled on this
call.   Does this make sense?

also, look into pointers, and pass them instead of the mods.  you can then
base your result set array/mods in the calling program on that pointer.

hth,

Rick

Clearing Multiple Occurs Datastruces is a performance issue  or not in case
you have 9999 limit for arrays and all of them are filled.

Program is not setting LR and all the variables / files are open for the
next calls?  What we do we only return the number of arrays we process next
time.

1. We processed 10 records we send 10 records in resultset
2. we processed 9999 records we send 9999 records in resultset
3. we processed 3 records we send 3 records in resultset

In the second request we filled 9999 arrays and they are still there in 3rd
request but we send only 3 records.

There is only one instance of this program but there could be 20-30 same
type of programs sitting in memory and processing arrays and return
resultsets. length of each array can be upto 500-1000 bytes

Thanks
