What about using a multiple occurrence data structure?

Booth,

A fine day I start coding one program, in which I am fetching records from
database file and based on certain conditions I am storing in array to
process in a batch.(Today I have only 5 records satisfying the criterion).
what you feel. Should I go for one more database file to store all selected
records if not what dimension I can choose for array ?? Say 500 but what
about a year after when the selection criterion start selecting 1000
records. I feel only solution is REDIM array if possible with RPGLE.

Don't suggest any other way to store records like open query or something..
my requirement may be to use arrays only.

I am asking myself the purpose of this redimensioning.  What does it do for
the programmer or the user that isn't done better and faster by using the
database?  A 20,000+ element array is getting pretty large and unwieldly.

The fact that Visual Basic redimensions arrays only points out the
shortcomings of being forced to do everything in volatile memory because the
Microsoft Operating System is so disjointed and unpredictable.  I find the
whole idea to be a weakness of Visual Basic and a strength of OS/400.

I am sure the error of my thinking will be pointed out, but please do so
courteously as I have a fragile ego this morning.

Exactly, I am asking same thing...I am not able to understand why this can
not be done in RPGLE..

Himanshu,

Are you asking for something like REDIM in Visual Basic, where you can
redimension an array on the fly (and preserve the existing array elements
if you want to)? The RPG gurus in my shop say it can't be done, but I'm
hoping someone here can prove them wrong.
