@CONSOLEB[handle] - create or restore a console screen buffer. "Handle" is the handle to the desired screen buffer. If "handle is -1, @CONSOLEB just returns the current buffer handle. If "handle" is 0, @CONSOLEB will create and activate a new console screen buffer. If "handle" is non-zero, @CONSOLEB will switch to that screen buffer. @CONSOLEB returns the handle to the active screen buffer. You can close an console handle with the @FILECLOSE function.
@CONSOLEB allows you to preserve the contents of the current screen buffer by switching to a second buffer temporarily and and then back to the original buffer.
