; PROCEDURE "NARRATIVE_MSG_ACCOUNTING"(NMACCNT).
;
; NARRATIVE:
; NMACCNT PERFORMES ALL ACCOUNTING REQUIRED FOR INBOUND MESSAGES/PSEU-
; DOMESSAGES RECIEVED FROM THE 'MSS' VIA THE 'NM'-QUEUE,OR OUTBOUND
; NICS-TARE MESSAGES RECIEVED FROM FIKS.
; 1.INBOUND NARRATIVE MESSAGES:
; THE CHANNEL NO RETRIEVED FROM THE MSG-FILE HAS BEEN VALIDATED,
; AND 'CCHNO' AND 'CMSGID' LOADED.'CMSGID' IS LOADED TO XINID.XACKTAB
; AND THE MSGID RETRIVED FROM THE MTCB (MPNM) IS LOADED TO XOUT.
; XACKTAB,EITHER IN ASCII OR DECIMAL FORM DEPENDING OF WHETHER IT
; IS AN EXTERNAL OR INTERNAL CHANNEL.
; 2.INBOUND PSEUDO MESSAGE:
; THE CHANNEL NO RETRIEVED FROM THE MTCB (MPNM) IS VALIDATED,AND IF
; VALID THEN XOUTID.XACKTAB IS UPDATED AS DESCRIBED ABOVE.
; IF AN ACK IS AWAITED(FEWAIT.ENTRY) NO FURTHER PROCESSING IS PER-
; FORMED.OTHERWISE IS THE DEFAULT VALUE HELD IN 'CMSGID' COPIED TO
; XINID.XACKTAB,AND A CALL IS MADE TO 'NMACKP' TO SIMULATE THE RE-
; CEIPT OF AN ACK.
; 3.OUTBOUND NICS-TARE MESSAGES:
; THE CHANNEL.NO (R0) IS VALIDATED,AND IF CH2 THEN 'CMSGID' IS LOADED
; TO 'XINID.XACKTAB(CH2)',AND THE ENTRY IS FLAGED WAITING.
