SCMCHL ;BP/DJB - PCMM HL7 Main Calling Point ; 16 Dec 2002  11:14 AM
 ;;5.3;Scheduling;**177,204,224,272,367**;AUG 13, 1993
 ;
 ;Reference routine: SCDXMSG
MAIN(MODE,XMITARRY,VARPTR,WORK) ;Main entry point to generate Primary Care HL7
 ;messages to NPCD in Austin. Loop thru PCMM HL7 EVENT file (#404.48)
 ;and generate HL7 message for each appropriate event.
 ;
 ;Input:
 ;  MODE     - Mode of operation.
 ;              1: Generate mode - Generate HL7 messages. (Default).
 ;              2: Review mode   - HL7 segments will be built in array
 ;                                 XMITARRY and may be reviewed. HL7
 ;                                 messages WILL NOT be generated, and
 ;                                 processed events will not be
 ;                                 removed from the transmit xref in
 ;                                 PCMM HL7 EVENT file.
 ;  XMITARRY - Array to store HL7 segments (full global ref).
 ;             Default=^TMP("PCMM","HL7",$J)
 ;   VARPTR  - For testing purposes, you may pass in an EVENT POINTER
 ;             value. This value will be used rather than $ORDERing
 ;             thru "AACXMIT" xref in PCMM HL7 EVENT file.
 ;             Examples:
 ;                "2290;SCPT(404.43," (Patient Team Position Assign)
 ;                "725;SCTM(404.52,"  (Position Assign History)
 ;                "1;SCTM(404.53,"    (Preceptor Assign History)
 ;   Work Optional if present
 ;Output: None
 ;
 ;Prevent multiple runs processing at the same time.
