Comment	See chapter 6 of the manual for the use of the "RSV" (reserve) mode. The "SML" key switches to small letters. The "P<>NP" key turns printing on or off, see "PRINT" annunciator in the display. "Help" displays a complete list of commands. Arrow up/down keys scroll thru this list. In case of an error "Help" displays some more information. The "MEM#" command returns 128 but it is not quite clear what this means.
