•To input a question mark (?), right arrow (→), colon (:), or output

command (^), press A ?, and then use number keys 1 through

4 to select the mark or command you want. See “Useful Program

Commands” on page 40 for more information.

4. Press t F F F 2 to exit program input.

u Program Storage Notes

•Use the syntax below to prompt for input of a value by the person running

the program, which will be assigned to the variable whose name is

indicated by the program.

?→ <variable name>

You can normally specify the variable names A, B, C, D, X, Y, and M

(independent memory). In the CMPLX Mode, however, you can use only

A, B, C, or M, because the other variables are used to store mode data.

•Use a colon (:) to link statements into multi-statements. A “statement” can

be a calculation expression or function (such as Fix 3 or Deg). Note that

you do not need to include a colon (:) at the end of the program.

• If you want execution of a program to pause at any point part way

through, insert an output command (^) at the end of a statement instead

of a colon (:). Note that you do not need to include an output command

(^) at the end of the program.

•You can also specify a mode when inputting a program. The mode you

specify is stored along with the program. You can specify different modes

for programs P1, P2, P3, and P4. While the Edit Prog screen in step 1

under “Storing a Program” (page 36) is on the display, use the F key to

specify the mode you want. The following are the modes that you can

specify for a program: COMP, CMPLX, SD*, REG*, BASE.

* Data input for statistical calculations is always retained in memory, even

after calculation is complete. Statistical data remaining in memory can

cause calculation errors when you run a program that includes statistical

calculations. Because of this, you should press A B 1

(Scl) <

before executing such a program, or you should include the Scl

command at the beginning of the program to make sure that statistical

data memory is cleared.

•During program input, the cursor normally appears as a flashing underline

mark (_). When there are eight bytes or less of memory remaining,

however, the cursor changes to a flashing black box (k). If the remainder

of the program you are inputting is larger than remaining memory
