Defining and changing console characteristics

When your system comes up, the definitions in certain members of SYS1.PARMLIB are in effect. After IPL, you can use CONTROL, MONITOR, SET, and VARY commands to change the definitions; however, the effect of the command lasts only for the duration of the IPL. To have an effect during the next IPL, the appropriate Parmlib member used for initialization has to be updated.
