•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.

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
