RE: Submiting an interactive job

[Peter Connell <peterc@xxxxxxxxxxxxx>]

kd,
We did this quite successfully when we had to implement a project where a
miniumum of redevelopment of existing code was required.  The intention was
to run the same code but output to a non-standard device, not a work
station.
If your solution does not require the code that interacts with the display
file, the simple solution is to make the display file an explicit open
operation by coding it as user controlled. If you monitor for the error
indicator on the open then this will be set on if the program runs in batch.
Although an exception msg is still raised and appears in the job log, the
pgm continues. Any code that relates to interaction with a display can
therefore be condtioned by the error indicator. This requires a minimal code
change for any pgm that is required for both interactive and batch
environments.
To extend this technique to output to an alternate device is more involved
but we did achieve this.
You can see that the major benefit here is that the environment in which the
pgm runs can be changed without necessarily having to understand or
reengineer existing legacy code that may contain arcane business rules.
 
Cheers,  Peter

Subject: Submiting an interactive job



Hi everyone,
 
 
Did anybody try with success to submit an display program in a batch ?
Normally a break message 'Device *REQUESTER not found while opening the
display file XXX' can be seen if the interactive application is running in
batch. The application I am interested in just displays some texts on the
screen and doesn't wait for the user input. So submiting it in batch seems
quite reasonable.
 
 
 
Thanks,
