XMAPHOST ;ISC-SF/GMB-Print to Message (P-MESSAGE) ;07/29/2003  14:36
 ;;8.0;MailMan;**2,17,21,28,33**;Jun 28, 2002
 ;Was (WASH ISC)/KMB/CAP before extensive rework.
 ;
 ;This routine handles printing to P-MESSAGE.
 ;
 ;To print reports to mail messages, we actually write to host files
 ;(DOS,VMS...) and then suck them into mail messages.  MailMan works
 ;closely with TaskMan and the device handler to make it happen.
 ;
 ;If a user or application wants to write something to a mail message,
 ;the user should choose (or the application should set ZTIO=) a device
 ;whose name starts with "P-MESSAGE".  The user or application can
 ;set the subject of the message, as well as the recipients.  The user
 ;does this by responding to MailMan queries, and the application does
 ;this by setting input variables (see below).
 ;
 ;EN^XMAPHOST is called as a pre-open execute for the P-MESSAGE device,
 ;and READ^XMAPHOST is called as a close execute for the P-MESSAGE
 ;terminal type.
 ;
 ;The pre-open execute is there to capture the wishes (message subject,
 ;recipients, and whether to queue or not) of the user working in the
 ;foreground.  The global ^TMP("XM-MESS",$J) is created, as a result.
 ;TaskMan looks for this global whenever $E(ZTIO,1,9)="P-MESSAGE", and
 ;includes it in the task, if the user chooses to task the print.  This
 ;is a special arrangement that MailMan has with TaskMan.
 ;
 ;If the job printing to P-MESSAGE is running in the background, then
 ;the pre-open execute code does not get executed during the pre-open
 ;execute; instead, it is run as part of the close execute.
 ;
 ;If more than 250 consecutive null lines are encountered, MailMan
 ;assumes EOF has somehow been missed, and stops transferring lines from
 ;the host file to the message.
 ;
 ;This routine has one idiosyncracy.  If the report contains one single
 ;line or two lines separated with only a $C(13) instead of a CR/LF that
 ;is more than 254 characters long, there will be unexpected results.
 ;
 ;Variables:
 ;input:
 ;  XMDUZ   (optional) Sender DUZ or string (default=DUZ)
 ;          If XMDUZ is a string, then user will not be asked who the
 ;          message should be from.
 ;  XMSUB   (optional) message subject.  If not supplied, then default
 ;          subject is "Queued mail report from "<user name>
 ;  XMY(x)="" (optional) array of additional addressees to whom the
 ;          message should be sent.  See documentation for ^XMD for more
 ;          info on XMY.
 ;          The message will always be sent to XMDUZ (unless XMDUZ is a
 ;          string), so it is not necessary to set XMY(XMDUZ)="".
 ;  XMQUIET (optional) if $G(XMQUIET), then there is no user interaction
 ;          and no information written to the screen.
 ;  XMZBACK (optional) if $D(XMZBACK), then XMZ is set upon exit,
 ;          and XMZBACK is killed.
 ;output:
 ;  XMZ     If $D(XMZBACK), then XMZ is set with the IEN of the message,
 ;          and XMZBACK is killed; otherwise, XMZ is not set, and
 ;          remains whatever it was (or wasn't) before the call.
 ;  XMMG    If error, may contain error message.
 ;  XMV("ERROR") If error, may contain error message.
 ;
EN ; Entry from pre-open execute of P-MESSAGE entry in DEVICE file.
 ; If the user chooses to queue the print, we don't want this code
 ; (the pre-open execute of the DEVICE file entry) to execute when
 ; the task starts up.
