callnat with long list of parameters

Hi
Any statistics of callnat performance with long parameters (thousands of fields?)
THANKS

Basically, performance degrades as the number of parameters increases. To be quite honest, i would have to check the manual to see if there is an upper bound on the number of parameters for a subprogram. “thousands” seems a bit unlikely; hundreds would certainly degrade performance quite a bit.

More commonly, you would pass a single large field that has been REDEFINE’d ;
for example

             1 #DATA (A500)
             1 REDEFINE #DATA
                2 #A1 (A10)
                :::
                2 #A100 (A3)

              CALLNAT 'MYSUB' #DATA

and MYSUB would have a Parameter Data Area with #DATA REDEFINE’d as above
