To specify an INFDS which contains fields in the open feedback section, you can make the following entries:
From = 81 + Offset To = From - 1 + Character_Length Character_Length = Length (in bytes)
For example, for overflow line number of a printer file, the Information Center gives:
Offset = 107 Data Type is binary Length = 2 Therefore, From = 81 + 107 = 188, To = 188 - 1 + 2 = 189. See subfield OVERFLOW in example below
