; ZEX 1.0 Installation ZEX File, 11-12-82, by Richard Conn
;
; You will need the following files in order to assemble ZEX:
; MAC.COM ZSID.COM ED.COM RELS.UTL
; Type <CR> if you have them on this disk or type ^C to abort -- ^/

;
; 1. ERASE ANY FILES FROM PREVIOUS .SUB EXECUTIONS
;
ERA ZEX*.BAK
ERA ZEX*.HEX
ERA ZEX*.SYM
;
; 2. USE CPM 2.2 XSUB (not required if using previous version of ZEX)
;
;XSUB
;
; 3. CREATE ZEX10.LIB FOR ASSEMBLY OF ORG 0 RELOCATED CODE SEGMENT
;
ED ZEX10.LIB
#A
#K
I
BASE EQU FALSE ;SUPPRESS ZEX INITIATOR CODE (ENABLE RELOCATED CODE)
REL EQU 0 ;SET RELOCATED CODE SEGMENT TO ORG 0
^Z
E
;
; 4. ASSEMBLE ONLY ORG 0 RELOCATED CODE SEGMENT
;
MAC ZEX $$PZ
;
; 5. RENAME STEP 4 FILES
;
REN ZEX100.HEX=ZEX.HEX
REN ZEX100.SYM=ZEX.SYM
;
; 6. CHANGE ZEX10.LIB FOR ASSEMBLY OF ORG 100H RELOCATED CODE SEGMENT
;
ED ZEX10.LIB
#A
#K
I
BASE EQU FALSE ;SUPPRESS ZEX INITIATOR CODE (ENABLE RELOCATED CODE)
REL EQU 0100H ;SET RELOCATED CODE SEGMENT TO ORG 0+100H
^Z

;
; 7. ASSEMBLE ONLY ORG 100H RELOCATED CODE SEGMENT
;
MAC ZEX $$PZ SZ
;
; 8. RENAME STEP 7 FILE
;
REN ZEX101.HEX=ZEX.HEX
;
; 9. CHANGE ZEX10.LIB FOR ASSEMBLY OF ZEX INITIATOR CODE ONLY
;
ED ZEX10.LIB
#A
#K
I
BASE EQU TRUE ;ENABLE ZEX INITIATOR CODE (SUPPRESS RELOCATED CODE)
REL EQU 0 ;RESET RELOCATED CODE SEGMENT TO ORG 0
^Z

;
; 10. ASSEMBLE ZEX INITIATOR CODE ONLY
;
MAC ZEX $$PZ
;
; 11. USE SID AND RELS.UTL TO CREATE ZEX.COM
;
; [note: If only REL.UTL is available, comment out the lines
; starting with IZEX.COM below and change the line
; SID RELS.UTL to SID REL.UTL and a SAVE 10 ZEX.COM
; must be added at the end of this file.]
;
; ZEX.HEX contains ZEX Initiator Code
; ZEX.SYM contains symbols for SID for ZEX Initiator Code
;
; ZEX100.HEX contains ZEX ORG 0 Relocated Code Segment
; ZEX100.SYM contains symbols for SID for ZEX ORG 0 Relocated Code
;
; ZEX101.HEX contains ZEX ORG 100H Relocated Code Segment
;
; BEGREL is the symbol for the start of the Relocated Code
; Segment in ZEX.COM
;
; DRVERL is the symbol for the length of the Relocated Code
; Segment
;
; DRVL8 is the symbol for the length of the storage required
; for the relocation table bit map to be created by
; RELS.UTL
;
; RELOCL is the symbol for the DW in ZEX.COM that will contain
; the length of the Relocated Code Segment
;
;
; A. SID is invoked and the .SYM files for the ORG 0 Relocated Code
; Segment and the Initiator Code Segment are loaded.
;
; B. The DW at symbol RELOCL is updated with the value of DRVERL
; from the ORG 0 Relocated Code Segment.
;
; C. Memory for the two copies of the Relocated Code Segment
; (ORG 0 and ORG 100H) and the relocation table bit map is zeroed.
;
; D. The ORG 0 Relocated Code Segment is loaded starting at
; location BEGREL.
;
; E. The ORG 100H Relocated Code Segment is loaded after the
; segment loaded in step C plus the length of the relocation
; table bit map.
;
; F. RELS.UTL routine SETADRS sets the starting addresses of
; the two Relocated Code Segments for creation of the relocation
; table bit map.
;
; G. RELS.UTL routine SETLEN sets the length of the Relocated
; Code Segment and builds the relocation table bit map.
;
; *H. RELS.UTL routine SAVE saves the EX Initiator Code Segment,
; the ORG 0 Relocated Code Segment, and the relocation table
; bit map created by RELS.UTL.
;
; * [note: not used if only REL.UTL is available]
;
; I. CP/M is returned to by G0.
;
; **J. SAVE 10 ZEX.COM saves the ZEX Initiator Code Segment,
; the ORG 0 Relocated Code Segment, and the relocation table
; bit map created by REL.UTL.
;
; ** [note: used ONLY if REL.UTL is used]
