;COPYRIGHT 1984, QMI, JS DeMar
;REV. 1.1, March 20, 1984
;OBJECT CODE RELOCATION GENERATOR for
;ACTION! compiled binary-load files.
;WARNING!!! This program requires
;four OPEN files simultaneously.
;Be sure that DOS is configured for
;this. With DOS 2.0, set $709 equal
;to at least 4, rewrite DOS and
;reboot.
;Requires the second file compiled
;at any even page increment higher
;than the first file, for example:
;$3000 and $3100.
;Generates a table of the locations
;that require relocating and saves
;it in a ".GEN" file in ACTION!.
; The ".REL" file is the original
;object code with an origin of "0".
;The actual relocator is compiled
;from the generic relocator source
;called "RELOC.ACT" merged with the
;".GEN" file generated here. Append
;".REL" file to that code and it
;will load and relocate to MEMLO.
