4STARTMSG(MSG,IEN,HDR) ;
5 ;Description: This function begins the parsing of the message, parsing
6 ;the header and returning the individual values in the array HDR().
7 ;Input:
8 ; IEN - The internal entry number of the message in file 773.
9 ;Output:
10 ; Function returns 1 on success, 0 on failure. Failure would indicate that the message was not found.
11 ; MSG - (pass by reference, required) This array is used by the HL7 package to track the progress of parsing the message. The application MUST NOT touch it!
12 ; HDR (pass by reference, optional) This array contains the results of parsing the message header.

31 ;Description: Advances parsing to the next segment and returns the parsed values from that segment.
32 ;Input:
33 ; MSG - (pass by reference, required) This array is used by the HL7 package to track the current position in the message. The application MUST NOT touch it!
34 ;Output:
35 ; Function returns 1 on success, 0 if there are no more segments in this message. For batch messages, a return value of 0 does not preclude the possibility that there are additional individual messages within the batch.
36 ; MSG - (pass by reference, required)
