;  Derivation:  ZZSOURCE and RESOURCE
;
; Original text:
;
;	DASM is a TDL/ZILOG Disassembler derived from Dave Barker's
; ZZSOURCE and Ward Christensen's RESOURCE by Richard Conn.  Refer to
; the documentation on RESOURCE and the built-in HELP data for information
; on the commands used for DASM.  A Help file is also being planned for DASM.
;
; Currently DASM consists of four files:
;
; DASM.LIB	This file: Main description library
; DASM8080.MAC	The INTEL 8080 Disassmbler part
; DASMZ80.MAC	The ZILOG Z80 Disassmbler part
; DASMKRN.MAC	The command manager part
;
; To build your favorite version do the following steps:
;
; Assemble	M80 =DASM??80	- Build the machine dependent part
;		M80 =DASMKRN	- Build the kernel
;	or	SLR80 DASM??80
;		SLR80 DASMKRN
; Link		L80 DASM??80,DASMKRN,myname/N/E
;	or	LINK myname=DASM??80,DASMKRN
;	or	SLRNK DASM??80,DASMKRN,myname/N/E
;
; NOTE: Always link DASMKRN as ** LAST** module
