Apparently a CESF ( signof) is given with an invalid option. I can reproduce the error by giving CESF <random string of chars> ( CESF BLABLA in my case ) The command is ignored, so you should be able to work. Else try a CESN to logon again. You might also ask your CICS-specialist about this. -- Maarten Slegtenhorst -----Oorspronkelijk bericht----- Van: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] Namens SUBSCRIBE IBM-MAIN gaa a. gamal Verzonden: woensdag 22 oktober 2008 11:29 Aan: IBM-MAIN@BAMA.UA.EDU Onderwerp: help unabel to logon to cics ceda or cemt Hi every body, when i logon to CICS sys to do CEMT or CEDA or other transaction, it gave me that massage: DFHCE3550 Sign-off option must be LOGOFF or GOODNIGHT.
