5STARTMSG(MSG,IEN,HDR) ;
6 ;Description: This function begins the parsing of the message, parsing
7 ;the header and returning the individual values in the array HDR().
8 ;Input:
9 ; IEN - The internal entry number of the message in file 778.
10 ;Output:
11 ; Function returns 1 on success, 0 on failure. Failure would indicate that the message was not found.
12 ; 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!
13 ; HDR (pass by reference, optional) This array contains the results of parsing the message header.

24 ;Input:

26 ;Output:
27 ; 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.
28 ; MSG - (pass by reference, required)
29 ; SEG - (pass by reference, required) The segment is returned in this array.

134 ; $$GET^HLOPRS(.SEG,1) will return the value of the first field, first
135 ; component, first subcomponent, in the first occurrence of field #1.
