Spool number of sumitted program

Hello,

does somebody know, how I can get the generated spool number of a submitted program?

Unfortunately, the system variables sy-spono or sy-sponr will be deleted, when the submitted program will be left.

Is it possibly feasible to get the spool number between the function modules 'JOB_OPEN' and 'JOB_CLOSE'?

Thanks a lot and regards.

Sergej
