m , [M-] , 1Kl and m terminate a calculation sequence, and a value entered following any of these keys begins a new calculation. Using the paperless printer, a calculation sequence is retained and can be recalled with PREV even after the display has been cleared with iiCCE until a new one is entered, or all steps are deleted using (m) .
