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.
