"Maximum number of screen calls was exceeded"

[Collings, Tony]

Thanks, Lorry.

 

Yes, each new instance of quick is run from a new AIX shell.

 

I'm aware of the screen levels parameter and we have this set to 15. I'm
not familiar with the concurrent screens parameter - this is the 'Screen
Table' field in the 'Execution-Time ...' screen, right? I've just
checked and it's set = the default 15. Although the description doesn't
appear to be directly related to the error, I'll try upping it to 50.

 

I'll let you know if it works out.

Not sure if different values for AIX PH8.4 but on VMS PH7.10, max screen
levels is 15 and max concurrent screens on display is 50. Both can be
set in the QKG execution time parameters.

Perhaps you could modify the code in order to log which screens are
being called and count how many levels deep.

Was each new instance of quick for each batch run under a new/separate
process?

 

Thanx

Forgot to add:

 

PH =  8.43G

O/S = AIX 6.1.0.0

Good afternoon all,

 

We have an application process that is producing the Max screen calls
error on an almost daily basis. A potentially large number of data
records are being processed in a single batch and each record in the
batch runs at least one, perhaps more, sub-screens = a correspondingly
large number of screen calls. The users of the application process stay
in the top-level screen, without exiting, processing batch after batch,
and the error occurs after the session has been active for several
hours. We've tried running a new instance of quick for each batch,
assuming the process counters would be reset with each instance and stop
the error being tripped, but we're still getting it.

 

Has anybody seen and dealt with the error? What was done to overcome it?

 

All suggestions/ideas welcome.

 

Thanks

 

Tony
