Begin to access the mainframe, learning to manipulate files. Erm data sets.
What really interesting is, the menu is suprisingly primitive.
Key board navigation? But it is simple enough. And some more advance features, like multiple panel, at one login.
Manipulating data sets have new rules. More rules than just simply creating file. But the editor is surprisingly quite advance. But is is productive, that need experience.
Honestly, other than windows, this must be a system, that break all the UNIX design methodology that I swore my self on.....
