I adjusted the Wiki field description to reflect the current code:

  If this field is non-zero a message is printed whenever this
  record is processed, and when any other record in the same
  lock-set is processed by a database link from this record.

I do like the idea of using TPRO > 1 to trigger debug messages from
record processing, and this could also be used by device support. It
should be up to the specific record/device support to document its usage
though.
