| 6 | message id | 0;6 | FREE TEXT | The unique ID for this HL7 message. | ||

| 14 | message type(+) | 0;14 | SET OF CODES | M:SINGLE MESSAGE B:BATCH OF MESSAGES F:FILE OF BATCHES | There are three types of messages as follows: M for Single message (contains only one MSH segment) B for Batch of messages (contains multiple MSH segments) F for File of batches (contains multiple BHS segments) This field is automatically filled in by the Messaging System and is used to determine the appropriate header segment to build for a message. | |
| 15 | don't purge | 2;1 | SET OF CODES | 1:DON'T PURGE 0:TO PURGE | When this field is set to 1, the message wil never be purged by the HL7 "Purge Message Text File Entries" option.

| 16 | namespace | 0;13 | FREE TEXT | This field must not be filled in manually. It will be filled in automatically by the HL7 processes that create entries in the HL7 Message Text file (#772).

When they do, they will pass by reference into the last OPTIONS (in the documentation) parameter the value of the namespace. The value of the namespace will be in the form of OPTIONS("NAMESPACE")=NAMESPACE. Please note that the calls to the three APIs mentioned above use the variable HLP to hold the passed in by reference array. So, in the HLMA code (and other code invoked by HLMA), the actual variable used is HLP("NAMESPACE"). This field is populated by UPDATE^HLTF0. | ||
