If you simply input the manual calculations shown above however, the calculator
would execute them from beginning to end, without stopping. The following com-
mands make it possible to interrupt a calculation for input of values and display of
intermediate results.
? : This command pauses program execution and displays a question mark as a
prompt for input of a value to assign to a variable. The syntax for this command
is: ?
→ .
^ ^ ^ ^ ^: This command pauses program execution and displays the last calculation re-
sult obtained or text. It is similar to pressing w in a manual calculation.
• For full details on using these and other commands, see “Useful Program Com-
mands”.
The following shows examples of how to actually use the ? and ^ commands.
