I would like to thank everyone who responded to my question about how to
check to see if a job is running or not.  The following is the final code
(using David Rutherford example):

::WHILE JSCOUNT("EMERCONJ,MGR.PHRIS&EXEC") > 0
::   ECHO ***************************************************
::   ECHO ** Another Employee Information Update  **
::   ECHO ** request is running.  Please wait for the    **
::   ECHO ** next update or press CTRL-Y to exit.       **
::   ECHO **

    **
::   ECHO ** Approximate wait is 10 seconds.              **
::   ECHO ***************************************************
::   PAUSE 10
::ENDWHILE

Thanks again,
Jeff
