If you set the calculator to step 118, press [ (MERGE], and pass the
card through the card reader, the instructions from the card will be
merged in beginning with step 119 and continuing through step 168.
(That is, 118 + 50 = 168). All instructions after step 118 will be
replaced in the original program, either by program instructions or
instructions from the magnetic card.
