Hi all, I'm a newbie in IBM z/OS and I have one problem: after successfully logging into the CICS (I see the message ' DFHCE3549 Sign-on is complete (Language ENU).') no matter what transaction names I enter I get the message of type: "DFHAC2001 11/02/2012 14:44:44 CICSZ057 Transaction '' is not recognized. Check that the transaction name is correct.". I enter my transactions in an upper-left corner of the screen. I would appreciate your help very much.
P.S. I'm sorry for possible mistakes, English is not my native language.
