The instructions for entering, running, exiting, and editing are the same for any program. The actual program on this sheet allows you to quickly evaluate a function. This may be helpful when determining a reasonable window for graphing or investigating the value of a limit.

Information that is printed within {} is not typed into the calculator. Usually this contains instructions for finding a particular command. Anything in RED denotes a button on the calculator. For example + is the addition button. Anything in BLUE denotes a button on the calculator that requires hitting another button first. For example the QUIT command will appear here as QUIT because you need to hit the 2nd button first.

Your calculator manual will be very valuable for finding the commands and buttons needed for programming.

How to enter a new program

Any words in the program that begin with an uppercase letter (Disp, for example) are actually commands and must be retrieved from a menu or key. In most cases the commands can be found using PRGM, DRAW, or TEST. Any words appearing in quotes are typed in letter by letter using ALPHA. If you need to delete a character use DEL. It deletes to the right of the cursor. If you need to insert characters use INS. It inserts to the left of the cursor.

The Program
This program has five lines. Hit ENTER at the end of each line. When you are finished, hit QUIT.
Lbl 1  {Lbl is in PRGM under CTL} {1 ia a one} 
Disp "X"        {Disp is in PRGM under I/O} 
Input X        {Input is in PRGM under I/O} 
Disp Y1  {Disp is in PRGM under I/O} {Y1 is in Y-VARS}
Goto 1  {Goto is in PRGM under CTL} {1 is a one}
