tranid
specifies the identifier of a transaction that you want to
test using the execution diagnostic facility. The
diagnostic panels are displayed on the terminal at which
you issue the CEDX

command.
The transaction you specify on the CEDX command
must run in the local CICS region.
CEDX cannot interrupt transactions that are already
running when you issue the CEDX command. It affects
only a transaction that starts
after
you issue the
command.
The following diagram illustrates the use of CEDX to invoke
EDF for a transaction initiated by an EXEC CICS START
command:
