SYNTAX            : ;W REG

RESULTING ARGUMENT: None except when requested register is '?'

FUNCTION          : Make the register immediately following the command 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.

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 (_) cannot be used.

NOTE 3            : To return to the original main buffer, use this command
                    with the name of the current register. If that name is
                    not known in the current context (e.g. in a macro), this
                    command also recognizes the name SPACE as name for the
                    original main buffer.

NOTE 4            : From within a register (say A), the main buffer is
                    accessable as if it were register A itself.

7.0:
NOTE 5            : To access the register as an array, a subscript can be
                    used.
