11. Text Display
You can include text in a program by simply enclosing it between double quotation
marks. Such text appears on the display during program execution, which means
you can add labels to input prompts and results.

?
”X =” ?

X = ?
• If the text is followed by a calculation formula, be sure to insert a display com-
mand ( ^) or multi-statement command (:) between the text and calculation.
• Inputting more than 13 characters causes the text to move down to the next line.
The screen scrolls automatically if the text causes the screen to become full.
