If a record with TPRO set is already active (PACT set) when it is asked
to process the message printed will say "Active"; if processing is
disabled with the SDIS/DISA/DISV mechanism the message will say
"Disabled". The normal "Process" message is printed immediately before
the record's process() routine is called.

Note that setting TPRO on one record also triggers messages from any
down-stream records that get processed synchronously through DB links
from that record — the downstream records must be in the same lock-set,
and get processed before the process() routine from the TPRO record has
returned.
