Problem:

I can setup the mapset name in the editor, but when you generate the maps, each overlays the preceeding generates.

I have 2 screens in AMB, Screen1 and Screen2. For each screen I define their mapset name as Scrn$. When I generate Screen1, it creates a file called Scrn$.BMS. I can see this in the MFEEE source/bms folder and it has Screen1 in it. Then I generate Screen2. It also creates a file called Scrn$.BMS which overlays the Screen1 map. Is there something in AMB, similar to the APS/MVS were you define a mapset, with the screens it contains, and you generate that instead of the individual screens?

Resolution:

It is possible to achieve the desired results if you are using the Distributed Generation Server (DGS). Using the parameters in the JCL to specify the desired mapset name, you can override the value that is present in the screen internal parms by specifying the mapset name that you want. In this case, both screens would have Scrn$ but in your JCL submitted to the DGS you can override the mapset name with any value you want.
