I = 1 : Sppos = 0
DO WHILE I > 0
    I = INSTR(Sppos + 1, Nm$, " ")   'Get position of next space.
    IF I > 0 THEN Sppos = I
LOOP
 
'SPPOS now points to the position of the last space.
IF Sppos = 0 THEN
    PRINT Nm$                        'Only a last name was input.
ELSE
    'Everything after last space.
    Lastname$ = RIGHT$(Nm$, LEN(Nm$) - Sppos)
    'Everything before last space.
