UPOC – iterate trough all the fields in any VRL

Hi,

Is there a way I can iterate trough all the fields in any VRL without using the field names using GRM ?

What I am trying to do is to map an HL7 to a vrl record ( with comma as FS) and use the UPOC protocol to write to an SQLite DB. I want the UPOC Write procedure to be generic that it basically inserts any vrl record into the appropriate table in the DB.

Thanks

Anwar
