Group Jobs allows you to have many interactive jobs opened at the same time that you can access by pressing on
the attention key. I just came up with a Group Job menu written in CL (no RPG) that permits to access your different jobs. We must first set up a PF called GRPJOBP, a display file called GRPJOBDF, a CLP called GRPJOB, a CLP called GRPJOB# and a CLP called GRPJOB##. Finally, we have to enter the command SETATNPGM GRPJOB. Every time we will hit the Attention Key, the program GRPJOB will be called displaying the Group Job menu.
