Parameter

process-name

   Requires that the process be in your group.

   Specifies the name of the process to be deleted. The process name
   can have from 1 to 15 alphanumeric characters. If the process-
   name includes spaces or lowercase letters, enclose the name in
   quotation marks (" ")  to preserve the correct spelling.

   The specified process must have the same group number in its
   user identification code (UIC) as the current process; you cannot
   use the process-name parameter to stop a process outside of your
   group. To stop a process outside of your group, you must use the
   qualifier /IDENTIFICATION=pid.

   The process name is incompatible with the /IDENTIFICATION
   qualifier; if you use the /IDENTIFICATION qualifier, the
   process name is ignored. If you include neither the process-
   name parameter nor the /IDENTIFICATION qualifier with the
   STOP command, the image executing in the current process is
   terminated.
