Recovery. Isolate and correct the problem within the SCREEN COBOL program. For
instructions on how to locate the problem within the program, see Additional
Information for Terminal Errors on page 12-3.
If a USER CONVERSION clause is used in the program, check the user conversion
routine.
3176: ZPWY-ERR-TCP-UNSOLNOTREPLIED
A SCREEN COBOL program unit attempted to receive an unsolicited message before
replying to a previous message. The program unit must execute the REPLY TO
UNSOLICITED MESSAGE verb before attempting to receive another unsolicited
message.
This error does not appear in the RETCODE token or in an error list; it appears only in
response to a STATUS TCP or STATUS TERM command.
Effect. The operation fails.
Recovery. Isolate and correct the problem within the SCREEN COBOL program. For
instructions on how to locate the problem within the program, see Additional
Information for Terminal Errors on page 12-3.
3177: ZPWY-ERR-TCP-UNSOLNONETOREPLY
A SCREEN COBOL program unit attempted to reply to an unsolicited message that did
not exist.
This error does not appear in the RETCODE token or in an error list; it appears only in
response to a STATUS TCP or STATUS TERM command.
Effect. The reply attempt fails.
Recovery. The REPLY TO UNSOLICITED MESSAGE verb should be used only after
successfully receiving an unsolicited message. Isolate and correct the problem within
the SCREEN COBOL program. For instructions on how to locate the problem within
the program, see Additional Information for Terminal Errors on page 12-3.
3178: ZPWY-ERR-TCP-MAXINPUTMSGSZERO
A SCREEN COBOL program unit attempted to receive an unsolicited message, but the
terminal was not configured for unsolicited messages (the ZMAXINPUTMSGS field in
ZPWY-MAP-DEF-TERM has a value of 0).
This error does not appear in the RETCODE token or in an error list; it appears only in
response to a STATUS TCP or STATUS TERM command.
Effect. The operation fails.
Recovery. Configure the ZMAXIMPUTMSGS field for the associated TERM or PROG
object to a value greater than zero.
