Job Processing States 

Jobs can pass through several processing states, but sessions pass
through only three:  EXEC (executing), EXEC*, and INTRO. Job processing
states are described in Table 3-1, below.  Not all jobs pass through the
same states.

The system keeps track of introduced, executing, suspended, waiting, and
scheduled jobs.  All processing states are displayed unless a particular
state is specified in the command syntax.  For example:  SHOWJOB WAIT. If
no jobs are waiting, the message NO SUCH JOBS will appear on the user's
terminal.  The same message also appears if the user requested status on
a job that has already finished or passed through the processing state
requested.
