	TITLE DMM Mail Munger -- TOPS-20 mailsystem
	SUBTTL Written by Michael McMahon /MMcM/TAH/SMC/MRC/TCR/KLH

;Version # stuff

VWHO==0				;Who last edited (0=MM developers)
VMAJ==6				;Major version (same as TOPS-20)
VMIN==1				;Minor version
VEDIT==33^D1097			;Edit number, MM.EXE should be same

;  The original version of MM was written by Michael McMahon at SRI
; International, presently at Symbolics.  At the time, it used a unique
; command parser designed by McMahon (ULTCMD), and had a similar user
; interface to the then-popular Tenex MSG program.  Stuart McLure Cracraft
; was also involved in early MM development and was primarily responsible
; for early popularizing of MM.
;
;  In the summer of 1978, a version of MM came to DEC.  Ted Hess at DEC
; converted it to MACRO and to use the COMND% JSYS instead of ULTCMD.
; At this point, MM and the program which was later to become DECmail/MS
; diverged.  Today, the difference between the two is that MM is free
; and has had continuous development.  DECmail/MS costs $15K and hasn't
; been touched much in the past few years.
;
;  Since the summer of 1979 most of the MM maintainence and development
; has been done by Mark Crispin, with occasional contributions from others
; too numerous to name.  MM has matured to become the standard mailsystem
; on most of the existing TOPS-20 systems.  Extensive input from its
; numerous users has made MM a powerful and reliable mailsystem.
;

;;;^N interrupt (abort) routines
; How to use the abort routines:
;  Abort handling is set up in a structured fashion, so that low level
; routines can handle aborts without the higher level routines knowing
; about them.  Likewise it is possible for routines to "undo" some things
; when aborted, before passing the abort higher up.  In the simplest
; case an abort will just set a flag which the routine can check when it
; gets around to it.  All this is done by means of an abort stack, APDL.
; Note that control-N can be be either "armed" or disabled without
; affecting the abort stack.  An "abort" is usually but not necessarily
; generated by a control-N; in particular, the ABORET routine will trigger
; an abort.  All aborts, at all levels, can be disabled by clearing ABOCAN.
;
;	To initialize, CALL ABOINI.  ^N is left turned off.
;	To specify an abort vector:
;		SETABT <loc> ;The previous abort vector is pushed.
;			;An abort will reset P to its value at
;			;the time SETABT was done, and jump to <loc>.
;	To unspecify a vector:
;		RET	;Restores the previous vector and returns.
; Flags:
;	ABORTF - set when aborted but vector is null.
;		Cleared by ABOINI and by dispatch to a non-null vector.
;	ABOSTS - state of ^N.  0 = enabled, -1 = disabled.
;		Saved by SETABT, restored by RET if ABOCAN permits it
;		Also restored by abort, but actual ^N state will be off.
;	ABOCAN - 0 = keep ^N and aborts off, -1 = can abort.
;
; An abort will:
;	(1) ask the user for confirmation, if appropriate
;	(2) pop the abort stack, restoring:
;		PDL ptr saved from SETABT
;		^N state saved from SETABT
;	(3) turn off ^N without altering "^N state", which now indicates
;		whether it is OK to turn ^N back on or not.
;	(4) dispatch to the popped abort vector.
;
;	The routine vectored to is responsible for re-enabling
;	and/or propagating aborts by calling ABORET, since
;	^N has been turned off to ensure the routine isn't
;	itself clobbered until it's ready.  If all levels call ABORET,
;	an abort will percolate back up to the topmost layer in controlled
;	fashion.
;
; Turning aborts off:
;	The good way to turn aborts off within a section of code is:
;		SETABT
;		CALL ABNOFF
;		... code ...
;		RET
;	This is better than simply calling ABNOFF because the previous
;	abort state is saved and restored.  E.G. just doing ABNOFF and
;	then ABNON would lose if aborts had been off prior to ABNOFF!
; ABOINI - Initialize abort routines.  Clears stack, leaves ctl-N
;	turned off.  Does not touch ABOCAN.

ABOINI:	CALL ABNOFF		;Turn off control-N first
	SETZM ABOPDP		;Clear abort stack
	SETZM ABOIP		;Clear abort-in-progress flag
	SETZM ABORTF		;And abort-seen flag
	RET

; SETABT <loc>	- set abort vector, save PDL
;	If no argument, default is that aborts just set the ABORTF flag.
;	A routine can then just periodically check this with a SKIPGE.

; OVERVIEW
;	There are two different kinds of keywords that MM understands.
; To distinguish them, they are called "keyflags" and "keywords".  The
; keyflags are what MM used to call keywords -- they are bit flags set
; in the preamble to the message, and are only meaningful on a per-user
; basis.  The number of these flags is limited to 30.
;      By contrast, keywords are text strings appearing in the "Keywords"
; field of the message header.  These are per-message and stay with it.
; There is no limit to how many keywords a message can have.  MM knows
; how to add and delete keywords (in effect modifying the message header);
; in some cases MM can insert extra spaces so as to leave room for
; easily adding new keywords later without having to change the overall
; length of the message.

; When keywords are specified by the user, they are stored in a keyword
; list of cells; each keyword cell has the format
;		cell:	<# chars>,,<addr of next cell>
;			<byte ptr to string>
; Keyword strings are not necessarily terminated with a null, since
; sometimes the string may reside in a read-only page of the message file.
; The "find" list is used when putting together a message sequence; the
; "modify" list is used when adding or deleting keywords.  Both may
; be active simultaneously.
