The Program Menu and Program Editing
Now that we have been through some short examples, let us look at some of the programming details.
The Program menu displays a list of the ten programs that are in the calculator. Use the >
and <keys to scroll through the program menu. For each program, the number displayed
at the bottom is the memory space used/occupied by the program and a checksum value of that program. For example, program 0 for the sphere uses 13 bytes and has a checksum of 104 (see Figure 2).
Figure 2
There are 290 bytes of program space available.
