When recording an unconditional branch always follow the
key with two digit keys to designate the step number. For in-
stance, to branch to step 6 the program instruction must be
G [o]fe].
If the first digit key following is greater than four, the
key is ignored and the number is stored in that step of pro-
gram memory. Similarly, if one of the two keys following [Ei
is not a digit key, the [ key is ignored and the invalid key is
stored in program memory.
Example Program. The following program is an interesting
one to show your friends. It calculates the squares of consecu-
tive whole numbers beginning with zero. The calculator con-
tinues to compute the square of the next consecutive whole
number until you press[R/S]to stop program execution (or until
the calculation overflows). The simple formula used is: x X n?
where n is continually incremented by one.
