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 menu
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)
