SYNTAX            : ARG ;W

RESULTING ARGUMENT: None

FUNCTION          : Make the register indicated by the argument the current
                    register. All commands up to a further ;w-command
                    operate with the named register as current buffer.

                    In interactive mode, the window title shows the name of
                    the active register (whenever there is one), and the
                    text area reflects the content of the register.

ARGUMENT          : The ASCII-value of the register.

NOTE 1            : If the specified register is numeric, its content is
                    lost. The register switch will occur as if the register
                    contained an empty buffer.

NOTE 2            : The special register associated with the current search
                    string (_) (ASCII 95) cannot be used.

NOTE 3            : From within a register (say A), the main buffer is
                    accessable as if it were register A itself.
