;   7(5)  [ti-12]  Fix bug in "DELETE {file} (from) {mailing list}"
;                    code which RLJFNed the JFN for the file to-be-deleted

; REASON: [ti-2] To correct problem with not being able to add network

;                 (local) user id existed.
;         
;<FORDYCE.SOURCES>MLIST.MAC,  24-Jun-82, Edit by FORDYCE

;   6(^d13)         
;
;<FORDYCE.SOURCES>MLIST.MAC,  18-May-82, Edit by FORDYCE
; REASON: To change references to SYSTEM:DECNET-HOSTS.TXT to
;   6(^d12)  SUB:MLIST-DECNET-HOSTS.TXT because I don't want to
;            take the time now to modify the ...HOSTS.TXT file

;            PATTERMANN from PMTTAB.
;
;<FORDYCE.SOURCES>MLIST.MAC,  6-Feb-82, Edit by FORDYCE
; REASON: To correct problem with individual users' logical names

;            mailing lists, instead of the true file spec.
;
;<FORDYCE.SOURCES>MLIST.MAC,  21-Dec-81, Edit by FORDYCE
; REASON: To correct problem with protection code getting set too
;   6(^d10)  strict when new SUB:MLIST.PMAP file is created.
;
;<FORDYCE.SOURCES>MLIST.MAC,  5-Dec-81, Edit by FORDYCE
; REASON: To increase the maximum number of 'users' per mailing list
;   6(^d9)   from ^d50 to ^d100. Increased the size of the PMAPed file
;            SUB:MLIST.PMAP to handle the increase in the maximum number
;            of users per mailing list.
;
;<FORDYCE.SOURCES>MLIST.MAC,  25-Nov-81, Edit by FORDYCE

;           Removed Miller from pmttab:

; REASON: Add the PURGE command to do the following:
;   6(^d7)  1) delete a user from all mailing lists, or
;           2) guide the user through the mailing lists that he is on,
;               asking for yes or no
;
;<FORDYCE.SOURCES>MLIST.MAC,  29-Jul-81, Edit by FORDYCE
; REASON: Modify 're-initialization' code so that when the mailing list
;   6(^d6)  data base is out of sync with the MLIST: directory, MLIST submits
;           a batch job to do the re-initialization, instead of requiring the
;	    user to wait while the re-initialization is done.  The batch job
;	    notifies the user when the re-initialization is complete.
;
;<FORDYCE.SOURCES>MLIST.MAC,  21-Apr-81, Edit by FORDYCE
; REASON: Add ALL option to "SHOW USERS" to show all the users for all the
;   6(^d5)  mailing lists.
;
;<FORDYCE.SOURCES>MLIST.MAC,  20-Feb-81, Edit by FORDYCE
; REASON: If the site using MLIST does not have DECNET and/or the
;   6(^d4)  file PS:<SYSTEM>DECNET-HOSTS.TXT containing DECNET node
;	    names does not exist, then proceed as normally, but don't
;	    try to parse a network address.
;
;<FORDYCE.SOURCES>MLIST.MAC,  9-Feb-81, Edit by FORDYCE
; REASON: (1) To modify the break mask when parsing the file name 
;   6(^d3)     of a mailing list so that periods are allowed (this was 
;	       inadvertently changed during modification to allow network
;	       addresses)
;         (2) To allow the addition of network addresses ONLY to mailing 
;	       lists which DO NOT have mailing list names (i.e. of the format
;	       'Mail-list:' . This is a restriction brought about by MM's
;	       net-mail capabilities).
;
;<FORDYCE.SOURCES>MLIST.MAC,  29-Jan-81, Edit by FORDYCE
; REASON: To check if the user is authorized to do a MUNGE BEFORE
;   6(2)    the %cmnoi
;
;<FORDYCE.SOURCES>MLIST.MAC,  21-Jan-81, Edit by FORDYCE
; REASON: (1) To permit the user, during the VERIFY command, to
;   6(1)       delete an invalid user or file spec from a mailing list
;         (2) To increase the flexibility of the ADD command -
;	       allow the user to add a network address to a mailing list
;         (3) To provide verification of the network address that
;              is being added to a mailing list
;
;<FORDYCE.SOURCES>MLIST.MAC,  5-Jan-81, Edit by FORDYCE
; REASON: (1) To add a new command - 'VERIFY', which allows the user to
;   6(0)       check the validity of entries in a mailing list(s) . 
;         (2) To correct the problem of parsing mailing lists with
;              mailing list names but without entries.
;	  (3) To allow the 'DELETE' command to delete entire mailing
;	       lists.
;
;<FORDYCE.SOURCES>MLIST.MAC,  3-Dec-80, Edit by FORDYCE
; REASON: To allow the user to delete obsolete file specs from
;   5(4)   mailing lists (i.e. alter the break mask for .CMFLD
;          to exclude the following characters:
;          !   %   *   .   :   <   >

;<FORDYCE.SOURCES>MLIST.MAC,  25-Nov-80, Edit by FORDYCE

; REASON:  (1) To open the MLIST data base with thawed access
;   5(1)        to allow simultaneous to the data base by 
;               multiple users
;          (2) To correct problem with DELETEing the last entry
;               from a mailing list and then ADDing another entry

;	        file

;*************************************************************************
;
;   MLIST was written for the purpose of providing some "automated"
; means of maintaining mailing lists, as used by MM and BABYL.
;
;   MLIST support for mailboxes was extracted from MMAILR/MMAILBOX
; (from the MM Mail System, courtesy of Stanford University).
;
;*************************************************************************
;*                                                                       *
;*   DISCLAIMER:  This was my "very first" experience with programming   *
;* in DEC-20 MACRO, so please excuse any glaring coding oddities.        *
;* Although I have enhanced MLIST over the last couple of years, I have  *
;* left all the code that worked alone.                                  *
;*                                                                       *

comment \

xitflg: on to indicate that an exit has been requested.

rscflg: on to indicate that the command line contains data other
	than the name of this program (MList) which may be parameters
	to feed to this program.

strflg: on to indicate that a <*structure|user-name|file name> is
	included as part of the mailing list, so let the first ":"
	that is encountered be treated as another ordinary alpha-
	numeric character

flag2:  on to indicate that a mailing list entry (i.e. a user name)
	is of the format '*ps:< user name > abc.xyz'. 

fstnam: on to indicate that the next mailing list name will be the
	first asciz string added to mmnams: , so do not do any 
	calculations to determine the address at which to begin 
	storing the string. Store the asciz string beginning at 
	address mmnams+1 .

colflg: on to indicate that the current mailing list being processed
	does not contain an actual name of a mailing list of the form
        '<name>:'. (This mailing list is probably obsolete ?)

gotusr: on to indicate that a non-blank user is currently being 
	parsed; or has been immediately followed with a blank rather
	than a comma.

gotnam: on to indicate that the name of a mailing list (as found in
	a file containing a mailing list) is being parsed.

anynam: on to indicate that the current mailing list does contain a
	mailing list name, whether or not it has any entries.

anyusr: on to indicate that at least one "user" has been found in
	the mailing list that is currently being parsed. 

anylst: on to indicate that at least one mailing list containing the
	user-specified user name has been found.

anymng: on to indicate that MUNGE was performed. If MUNGE WAS performed,
	a new version of the mailing list data base was created in
	the pages beginning at location 500000. So PMAP these pages from
	process to file to make this copy of the mailing list data base
	permanent instead of UNmapping the process pages to the file.
	 If MUNGE WAS NOT performed, the mailing list data base was
	PMAPed from the file containing the permanent copy of the mailing
	list data base into the process pages beginning at location 500000.

anydbs: on to indicate that a mailing list data base DOES exist.

anymap: on to indicate that the mailing list data base is mapped from
	the permanent copy in the file to the process pages. Off to 
	indicate that the next time that the file containing the mailing
	list data base is closed, the process pages should be mapped
	from process pages to file, rather than simply UNmapped.

dirmng: on to indicate that the MUNGE requested was the result of
	of an invocation of the MUNGE command of MLIST, rather than a
	result of the file (containing the mailing list data base)
	not existing.

delflg:	on to indicate that during the process of trying to match
	a user input user name - file spec, that the particular
	user name - file spec has already been deleted from the
	file once, so do not try to delete the user name - file
	spec more than once on a single pass through the data base's
	'map' of the file.

delopt: on to indicate that the DELETE option is being invoked.

renopt: on to indicate thet the RENAME option is being invoked.

a:	on to indicate that an ADD was invoked during this execution
	of MLIST (for LOG purposes only).

c:	on to indicate that a CREATE was invoked during this execution
	of MLIST (for LOG purposes only).

d:	on to indicate that a DELETE was invoked during this execution
	of MLIST (for LOG purposes only).

h:	on to indicate that a HELP was invoked during this execution 
	of MLIST (for LOG purposes only).

match:  on to indicate that corresponding names of files ( MLIST data
	base VS. MLIST: ) that contain mailing lists are equal. This
	flag is used to indicate whether or not a new mailing list
	was created WITHOUT USING MLIST (i.e. by using EMACS, or some
	other editor instead), or if a previously-existing mailing
	list was deleted from MLIST: , but information from that
	particular mailing list is still resident in the MLIST data
	base.

dodel:  on to indicate that during a pass through the entries in
	a mailing list (as contained in the MLIST data base) looking
	for the entry that is to be deleted, the entry has been
	located and "deleted".

badusr: on to indicate that during a VERIFY, the current mailing list
	being processed contains at least one invalid user (either a
	non-existent file or an invalid user name);
	OR during an ADD, that the "user" that is being added to a
        mailing list is an invalid file spec, which MLIST will not
	allow.

badfil: on to indicate that during a DELETE, the obsolete user that is
	to be deleted from a mailing list is a file spec, so precede
	it with a '*'.

anyhst: on to indicate that a file ( PS:<SYSTEM>DECNET-HOSTS.TXT )
	exists containing DECNET network node names.

dirnos:	an area to store users (i.e. user numbers or addresses of asciz
	strings (in mmnams:) specifying file specifications or obsolete
	users (users for which a user number no longer exists) which
	make up each mailing list.

        Within dirnos, a header word is associated with each mailing list.
        Each header word is of the format:

   (number of entries - i.e. users   (ptr to an associated asciz string
    in the associated mailing list),, containing the name of the mailing
				       list, if any)

        Each of the other words within dirnos contains a user number
        specifying a user who is a "member" of the mailing list specified by
        the associated header word, or an address (in mmnams) of an asciz
        string file specification (preceded by an asterisk) or an obsolete
        user for which a user number no longer exists.


jfndir:	a (tbluk) keyword table - 
	an area to store, for each mailing list, the address (in filnam:)
	of the asciz string specifying the name of the file containing
	the mailing list, and the jfn associated with that particular
	file (during this execution of MLIST)

        Within jfndir, a header word is associated with all of the mailing
        lists combined.  This header word is of the format of word 0 of a
        tbluk table - i.e. the left half contains the actual number of
        entries in the table, and the left half contains the possible number
        of entries in the table.

        Each of the other words within jfndir is of the format:

        (addr. of the file name,     (jfn of the file containing
         in filnam, containing   ,,   the mailing list)
         this mailing list)        


mmnams: an area for storing asciz strings specifying the names of mailing
	lists and for storing asciz strings specifying obsolete users for
	which user numbers no longer exist.

filnam: an area for storing asciz strings specifying the names of the
	files which contain the mailing lists.

namtab: a (tbluk) keyword table 
	an area for storing, for each mailing list, the address (in filnam:)
        of the asciz string specifying the name of the file containing the
        mailing list, and the address of the header word (in dirnos) for
        that mailing list

        Namtab has a header word associated with the (tbluk) keyword table
        as a whole.  This header word is of the format of word 0 of a tbluk
        table - i.e. the left contains the number of actual entries in the
        table, and the right half contains the number of possible entries
        in the table.

        Each of the other entries in the table is of the following format:

        (addr. of the asciz string      (addr. of the header word, in dirnos,
         name of the file containing  ,,   for that particular mailing list)
         that mailing list)
