| Parameter | Type | Description | ||||||
| docRef | DocRef |
|
Document reference number | |||||

This command operates only on a document currently open whose document reference number you pass in docRef.
SET DOCUMENT POSITION sets the position you pass in offset where the next read (RECEIVE PACKET) or write (SEND PACKET) will occur.
If you omit the optional anchor parameter, the position is relative to the beginning of the document. If you do specify the anchor parameter, you pass one of the values listed above.
Depending on the anchor you can pass positive or negative values in offset.
