			R U N N L . D O C
			=================

	RUNNL is a program which will spawn a task on the privileged TI of
device NL0.  In order to use, you must have included this device in your
SYSGEN command file, though it need not have any device handler associated
with it.  RUNNL handles all task scheduling requests sequentially, and
will not schedule a second task until the first has exitted.  Where possible,
therefore, tasks which may take more than several seconds should be started
by spawning ...RUN with a command line to run the desired task.

	When you bring your timesharing system up, RUNNL must be initiated
by typing:
		SCI> INS RUNNL
		SCI> RUN/REAL .RUNNL NL0

	The task remains active, in a stopped state.

	To spawn a task, you must call the FORTRAN IV Plus routine SPWNNL:

	CALL SPWNNL(TASK,IOP,COMLIN,COMLEN,DSW)
C
C  INPUTS
C	TASK - TASK TO SPAWN (2 WORDS: 6 CHARACTER RAD50)
C	IOP - 4 WORD OPTIONAL PARAMTERES AS PER SPAWN
C	COMLIN - COMMAND LINE TO PASS TO SPAWNED TASK
C	COMLEN - LENGTH OF THE COMMAND LINE
C
C  OUTPUTS
C	DSW - DIRECTIVE STATUS
C	RETURNS AFTER THE SPAWNED TASK HAS EXITED
C

To build:
---------

	Execute the command files:
		RUNNL.CMD
		SPWNNL.CMD

Prerequisites:
--------------
	IAS V3.0 timesharing
	FORTRAN-IV Plus V2.5
	NL0 declared as device in SYSGEN
