program. If ON ERROR clause is not mentioned, then TCP aborts the terminal after
logging the error against the term. If the term is associated with any dialog, the dialog
is also aborted.
Recovery. Recovery is application specific. Since TCP does not know the status of
the last I/O hence the SEND/DIALOG operation can be retried if it is OK to send
duplicate message to the server class. Pathway/iTS 1.1 strongly recommends that the
send and dialog operations to server classes that don’t allow duplicate messages must
be wrapped under TMF transactions.

Cause. The context sensitive programming protocol has been violated by the
SCREEN COBOL program. The possible causes of this error are:
•
A second DIALOG-BEGIN was attempted when the term is already under active
dialog.
•
A DIALOG-SEND was attempted without the term being under active dialog.
•
A DIALOG-END was attempted without the term being under active dialog.
•
A DIALOG-ABORT was attempted without the term being under active dialog.
Effect. The operation fails. If ON ERROR clause is mentioned, then error is reported
against the term but the term continues to run depending on the error-handling logic in
the SCREEN COBOL program. If ON ERROR clause is not mentioned, then TCP
aborts the terminal after logging the error against the term. If the term is associated
with any dialog the dialog is also aborted.
Recovery. There is no recovery action on this. Correct the SCREEN COBOL program
and restart the term. For instructions on how to isolate the problem within the program,
see Additional Information for Terminal Errors at the beginning of this section.
