:
The trace provides the following information. It shows:
• The location of each field in the ARB (Buffer offset);
• The length of each field in the ARB (Length);
• The type of transformation that occurs (Type);
• The value that is transformed in the ARB field (Value).
NOTE This ARB is tied to seven form fields, but there are gaps in the buffer before
field 1, and between each field from 2 to 6. These gaps are one-byte filler
fields.
