/PARAMETER BLOCK CREATION FOR DECSYSTEM-8/78 OR OS/8
/
/FORMERLY CALLED PARAM IN DECSYSTEM-8

/	1. PARAM BY D.E.WREGE   5/23/73
/	2. MODIFIED 5/23/74 TO REMOVE MONITOR VERSION
/	   DEPENDENCE.

/	  THIS VERSION WILL RUN STAND ALONE OR UNDER
/	 PS/8,OS/8,DS/8, OR ANY OTHER VERSION OF THE MONITOR.
/	 (R.H.)

/	3. 9/7/77  DEVICE TABLES EXPANDED AND CLUSTERED
/	        AT 3200, STARTING ADDRESS 200
/	4. SEQUENTIAL VOLUMES ADDED (DSH&WHT)

/	5. NAME CHANGED TO HEADER TO AVOID CONFLICT
/	WITH RTS/8 PARAM (WHT & DSH))
/	6. ADDED OS/8 V3D DATE IN EXTENDED HEADER DATE
/	USE DIRECT V5H OR V6A TO PRINT (WHT & DSH)

/VERSION 3D 12/31/77 NY WM. H. TOPLISS & D. S. HARMER
/TO ASSEMBLE:
/	.R PAL8

/TO LOAD AND SAVE:
/	.R ABSLDR
/	*HEADER$
/	.SAVE SYS:HEADER	/NOTE:SA=0200

/
/THIS PROGRAM IS PART OF DECSYSTEM-8/78 FOR THE INITIAL
/CREATION OF A PARAMETER BLOCK ON FILE STRUCTURED
/DEVICES. THE PRIMARY REASONS FOR DESIRING A PARAMETER
/BLOCK ARE:
/	TO CARRY THE DEVICE LENGTH ON THE MEDIUM
/	TO CARRY A LOGICAL USER DEVICE NAME
/	TO CARRY A UNIQUE VOLUME NUMBER
/	TO CARRY A DESCRIPTIVE LABEL
/	TO CARRY INFORMATION FOR INTELIGENT SQUISH AND ZERO.
/	TO PROVIDE A REFERENCE DATE FOR ARCHIVES
/	AND OTHERS TO BE DEFINED IN THE FUTURE.

/THE PARAMETER BLOCK WILL EXIST IN BLOCK 6 OF THE
/DEVICE, WITH PRESENCE BEING SIGNALLED BY THE FIRST 3 WORDS
/IN THE BLOCK.

/NOTE THAT IF THE SYSTEM EVER EXTENDS THE SYSTEM
/INTO BLOCK 6 THESE WORDS WILL BE REPLACED
/THUS REMOVING THE PARAMETER BLOCK.  THIS SHOULD
/SELDOM HAPPEN EXCEPT IN THE CASES OF RK8'S OR LOTS
/OF RFO8 DEVICES.  THE MOTIVATION IS THAT FILE STORAGE
/SHOULD TAKE PRECIDENCE, AND MOST USERS PROBABLY DON'T
/CARE IF SYS HAS A PARAMETER BLOCK ANYWAY.
