== Why is this an issue?

Both the name and the field definitions of a parameter 2 data area used in an ``++IN++`` should be coded in the ``++D++`` specification. This ensures that all definition data is kept together, and the specific data is not manually extracted in the code, thus making the code easier to read and maintain.
