Entering Program Commands

The calculator contains built-in programming commands on

three menus. You access these menus by pressing 8 from

the Program editor. The first two menus, the 8

CTL

and the 8

I/O

menu, are discussed extensively in the next

two sections. The third menu, the 8

EXEC

menu, lets you

call existing programs as subroutines. It is discussed in the

section entitled, Executing a Program.

Entering Functions, Instructions, and Variables

In the Program editor, you also can select from function

menus on the calculator (1, - ‚, etc.), change

settings (., - f, etc.), as well as select function

keys (=, 6, etc.). Simply press the appropriate key, and the

function, instruction, or mode setting is pasted at the cursor

location in the Program editor. Also, remember that all

instructions and functions are listed in the

CATALOG

(- |).

Programs can access variables and lists saved in memory. If a

program stores a new value to a variable or list, the program

changes the value in memory during execution.

The following menus or keystroke sequences change

appearance or operate differently when accessed from the

Program editor:

• 8 (accesses programming command menus)

• - e (changes appearance)

• - † (changes appearance)

• - f (changes appearance)
