Current Registers window

The Current Registers window is opened by entering the REGS or REGS64 command. It is closed by issuing the REGS or REGS64 command again or by issuing the CLOSE command against that window.

By default it displays the current PSW, the current general purpose and floating point registers. If the CREGS command was issued the current control registers are displayed. If the AREGS command was issued the current access registers are displayed.

You can modify the contents of the PSW or registers whenever they are displayed by overtyping the current information with the new value.
