MTRAPNEW.MEMO

New options in MTRAP:
 
   MTRAP LOADEXIT exitname <parms>
 
   Will load the RELOCATABLE MODULE exitname into freestorage and call it
   with the following PLIST
 
     R1-> CL8'exitname',CL8'INIT'<,parms>,8X'FF'
 
   MTRAP DROPEXIT exitname <parms>
 
   Will call the exitname with the following PLIST
 
     R1-> CL8'exitname',CL8'TERM'<,parms>,8X'FF'
 
   MTRAP CALLEXIT exitname <parms>
 
   Will call the exitname with the following PLIST
 
     R1-> CL8'exitname',CL8'CALL'<,parms>,8X'FF'
 
   Whenever a message is received the exit is called with the following
   PLIST
 
     R1-> CL8'exitname',cl8'MSG',AL4(msg,length,identify,names),8X'FF'
 
   Where:  msg is the address of the message text with all leading junk
                   truncated, like DMT and FROM and timestamp.
           length is the length of the text in characters.
           identify is the address of the following data:
                   CL8'myuserid',CL8'mynodeid',CL8'rscsid'
           names is the address of the following data:
                   CL8'nickname',CL8'fromuser',CL8'fromnode'
                   (possibly some other data, not yet decided on)
 
   the exit should return in R15 the following:
 
   -1 means that the message was not processed, MTRAP should try
      any further exit and if none are found just output it normally.
   =0 means that no further processing for this message is required.
   >0 is the address of a string al1(length),cl(length)'string' which
      should be output to the terminal using the MTRAP CPCONIO output
      facility.
   x'80',al3(address) is same as '>0' except that MTRAP will call
      the exit once more after output is complete to possibly generate
      more output.
 
Possibly MTRAP will require a filetype of MTRAP rather then MODULE for
its exits. MTRAP will DROP all exits when it is itself dropped.
 
Any suggestions are more then welcome.
