I am New to AFS ..While Using AFS

I am going for a record as :

stpapi.get.field("Session name ","Table field name", "variable name")

Argument 3 for function get.filed should be called by reference

All afs questions should go in this forum.

Below is a simple get.field example and I am not sure I understand what you are asking. Is your third field a string field?

string serial.number(6)
stpapi.get.field("tdilc1120m000","tdinv100.sern", serial.number)
