Checking different jobs within an ABAP program

Within an ABAP program, how can you check if another job with a particular job name is running? For instance, in my ABAP program, I want to see if there's a job called 'UPDATE_FILE' running. Is there a way to do this?

You can query table TBTCO (Job Status Overview) and determine if the value of the field "STATUS" is 'R' for active or running for the JOBNAME='UPDATE_FILE'.
Possible values in "STATUS" field are:
P Scheduled
S Released
A Cancelled
R Active/Running
F Ready

I believe this answers your questions. Please let me know.
