PARSE(MSGIEN,MSGID,CURLINE,ERRCOUNT,DGPAT,DGELG,DGENR,DGCDIS,DGOEIF,DGSEC,DGNTR,DGMST) ;
 ;Description:  This function parses the HL7 segments.  It creates arrays
 ;defined by the PATIENT, ENROLLMENT, ELIGIBILY, CATASTROPHIC DISABILITY,
 ;OEF/OIF CONFLICT objects.
 ;Field values are put in DHCP format and the validity at the
 ;field level is tested.  Fields to be deleted are set to "@".
 ;
 ;Input:
 ;  MSGIEN - the ien of the HL7 message in the HL7 MESSAGE TEXT file (772)
 ;  MSGID -message control id of HL7 msg in the MSH segment
 ;  CURLINE - the subscript of the PID segment of the current message (pass by reference)
 ;  ERRCOUNT - is a count of the number of messages in the batch that can not be processed (pass by ref)
 ;
 ;Output:
 ;  Function Value: Returns 1 on success, 0 on failure.
 ;  CURLINE - upon leaving the procedure this parameter should be set to the end of the current message.
 ;  ERRCOUNT - set to count of messages that were not processed due to errors encountered. (pass by ref)
 ;  DGPAT - array defined by the PATIENT object. (pass by ref)
 ;  DGENR - array defined by the PATIENT ENROLLMENT object. (pass by ref)
 ;  DGELG - array defined by the PATIENT ELIGIBILITY object. (pass by ref)
 ;  DGCDIS - array defined by the CATASTROPHIC DISABILITY object. (pass by ref)
 ;  DGSEC - array defined by the PATIENT SECURITY object. (pass by ref)
 ;  DGOEIF - array defined by the OEF/OIF CONFLICT object.  (pass by ref)
 ;  DGNTR - array defined for NTR data.
 ;  DGMST - array defined for MST data.

CONVERT(VAL,DATATYPE,ERROR) ;
 ;Description: Converts the value found in the HL7 segment to DHCP format
 ;
 ;Input:
 ;  VAL - value parsed from the HL7 segment
 ;  DATATYPE: indicates the type of conversion necessary
 ;      "DATE" - needs to be converted to FM format
 ;      "TS" - time stamp, needs to be converted to FM format
 ;      "Y/N" - 0->"N",1->"Y"
 ;      "1/0" - "Y"->1,"N"->0
 ;      "INSTITUTION" - needs to convert the station number with suffix to a point to the INSTITUTION file
 ;      "ELIGIBILITY" - VAL is a pointer to the national eligibility code file (#8.1), needs to be converted to a local eligibility code (file #8)
 ;
 ;      "MT" - VAL  is a Means Test Status code, it needs to be converted
 ;             to a pointer to the Means Test Status file
 ;       Phase II convert code to RSN IEN for DGCDIS object
 ;       "CDRSN" data type converts the codes diagnosis,procedure,condition to RSN IEN. (HL7TORSN^DGENA5)
 ;       "EXT" convert from code to abbreviation
 ;       "POS" convert from Period of Service code to a point to Period of Service file
 ;OUTPUT:
 ;  Function Value - the result of the conversion
 ;  ERROR - set to 1 if an error is detected, 0 otherwise (optional,pass by ref)
