;
; 11. USE SID AND RELS.UTL TO CREATE EX14.COM
;
; [note: If only REL.UTL is available, comment out the lines
; starting with IEX14.COM below and change the line
; SID RELS.UTL to SID REL.UTL and a SAVE 10 EX14.COM
; must be added at the end of this file.]
;
; EX14.HEX contains EX Initiator Code
; EX14.SYM contains symbols for SID for EX Initiator Code
;
; EX140.HEX contains EX ORG 0 Relocated Code Segment
; EX140.SYM contains symbols for SID for EX ORG 0 Relocated Code
;
; EX141.HEX contains EX ORG 100H Relocated Code Segment
;
; BEGREL is the symbol for the start of the Relocated Code
; Segment in EX14.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 EX14.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 EX14.COM saves the EX 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]
