>This question may be simple but i have no clear idea how TSO/E Logon procedure invoke while login ?
Without going too much into details, this is what happens for TSO LOGON - Your terminal is connected to VTAM (possibly through TCP/IP) - You select "LOGON TSO" from you screen (possibly via some sort of session manager) - Your request will be handled by VTAM which invokes LOGON processing with TSO's Terminal Control Address Space (TCAS). - TCAS prompts you for your userid, then presents you the logon screen. Here you enter our password, and specify the logon procedure (PROC) you want to use, as well as some more parameters. - TCAS verifies your password, and if correct, issues an internal LOGON command, which is similar to an operator START command. The logon procedure chosen will be used to start your personal TSO address space. Note that some or all of the above steps may be hidden behind automatic logon procedures implemented in the session monitor you use.
