Transmit a
program
You can send programs to, and receive programs from,
other calculators just as you can send and receive aplets,
matrices, lists, and notes.
After aligning the calculators’ infrared ports, open the
Program catalogs on both calculators. Highlight the
program to send, then press
on the sending
calculator and on the receiving calculator.

computer). This takes place via a cable connection and
requires an aplet disk drive or specialized software
running on a PC (such as a connectivity kit).
