The Header.txt file is the source of input card #1 HeaderFile.
The first data item in the Header.txt file is the customer number (in this case
customer number 4500) as described by Customer# Field item type in the
TwoFiles.mtt.
The trace file message for customer number 4500 is:
(Level 2: Offset 0, len 6, comp 1 of 4, #1, DI 00000001:)
Data at offset 0 ('4500 ') was found to be of TYPE
X'0008' (Customer# Field Data).
Trace Message Description
Level 2 The level of an object indicates the position of the
data object with respect to the entire card object.
A card object has Level 0; a component of the
card object has Level 1, and so on.
The Customer# Field Data item type is a
Level 2 because it is a component of the Header
Record, which is a Level 1. In this example,
HeaderFile is Level 0.
