How a CICS system is called from a 3270 terminal or emulator ?
Posted on 2011-02-20
Since our last interaction I've got access to a CICS printed material - describing the mainly commands and maps concepts, now it's much more clear the overall understanding.
But something remains obscure for me is: How a 3270 terminal calls the Cobol application (that has the menu - a CICS map) to start the process ?
Is it like a DOS program ? the user types de name of the system ? (eg. ACCOUNTS.EXE - sorry if it's a very dummy question...)
Every terminal in fact only receive via SNA what is hapenning at mainframe and interact by filling a map, ok ?
Every terminal must have TSO as IBM interface or only the developers ? if not the common users access is by what device ?
Is it possible to use more than one "system" concurrently at the same 3270 terminal or emulator ?
(say ACCOUNTS.EXE and PAYROLL.EXE ?)
Thanks in advance
