; rename this ENSPOOL.DOC to BYERSX.INC for assembly with RSXMAST
;
; This file is used to include data areas compatible with the exist-
; ing BYE programs.  A BYE replacement must always have "driver" set
; true, and "nodrive" set false.  When code is included here it will
; cause the replacement bios jump vector to be located higher than
; usual, which may cause problems with some programs that are care-
; less in calling the bios directly.  For most RSXs this file
; contains no code.
;
; ENSPOOL captures all LST device output (supplied via BDOS calls,
; not via BIOS calls), and creates an image spool file, which may
; later be printed with UNSPOOL.  All characters are captured,
; however UNSPOOL will not output an 01Ah character, which is treated
; as EOF.  This may create difficulties for graphics.
;
; Because BIOS calls are not captured, the ^P operation, for console
; output copied to lister, will still create immediate hard copy,
; and will not be routed to the spoofl (spoolfile).  Since BDOS is
; non-reentrant, and the system must use DOS to write to the file,
; it is impossible to capture these bios writes.  Application writes
; can be caught, and probably will be in a later version.  See the
; configuration of UNSPOOL for the fundamental method.
;
; This system is designed to work ONLY for list output via the BDOS
; call.  Direct bios calls will not be intercepted.  This program is
; a companion to UNSPOOL.  Mounts with RSX12.  To assemble rename 
; the various files as instructed (this file, RSXIO.ESP, RSXINIT.EST,
; RSXMAIN.ESP, and RSXCUST.ESP), and assemble RSXMAST.MAC from the
; RSX12 library.  All necessary files will be included.

; usage:
;   d>ENSPOOL [d:]filename[.typ]          to initiate
; or
;   d>ENSPOOL                             to remove and close file
;
; note that the created spoolfile will not be available to other
; utilities until closed by removing ENSPOOL.
;
; This system may be used to create exact output images with Word-
; Star.  Multiple copies may then be printed with UNSPOOL.  However
; WS likes to output strings of 01ah characters at page breaks, and
; thus this system intercepts and ignores them.  The only end-of-file
; marker is made by closing the output file (second run of ENSPOOL
; above).  Thus if the 01ah is ever used for printer control, trouble
; will be caused.
;
; TIP.  For WordStar images, WS has the habit of generating a 
; form-feed (character 0ch) at both the start and finish of a file
; print.  This wastes a sheet for each run, and is annoying.  When
; the spoofle has been made, load it into DDT, and scan the first
; few bytes (usually no more than 30) for an 0C.  Change it to an
; 0D with DDT, and then save the file again.  (you can also do this
; with DUU, or the equivalent).  This will remove the initial form-
; feed, and ease creation of multiple copies.
