SO, fundamentally, you want to emulate what an operator would do
WRKACTJOB, find the job, check its status.
You have defined job names
So write a function which will retrieve the jobs (There’s an API for this) and check for the jobs you are interetsed in. place the results in a data area.
put your job in the backgound, configurable to check at 2 minute intervals, or whatever, if a joh is unhappy, send email alerts, or text messages.
Provide a function which displays the data area(s) on screen, which can be called at any time, anywhere. Show the jobs on screen – green for OK, Flashing Red if the job is not there or on a message.
There is plenty of API example stuff on the ‘net, a bit of thought, with cut and paste, will get you there.
