Under CMS the program must execute a DIAGNOSE X'58' to clear the screen.
The instruction looks like this:
        DIAG  R3,R2,X'0058'
Where R3 is the address of a CCW and R2 is the console address.
Unlike Jerry Callen, I know CMS but not CCW's so here is the CCW's used
by a (not to be named) module: CCW     DC X'1900000060FF0001'
                                       DC X'0300000020000001'
I won't vouch for it validity, especially since I couldn't find the 19
command code listed anywhere.
