u Inputting and Editing Text Line Contents
•You can input up to 255 bytes of text into a text line. Scroll arrows (]') will appear on
the left and right sides of the text line to let you know there is additional text that does not
fit within the text line display area. In this case, you can use the left and right cursor keys
to scroll the text.
• The 5(A↔a) function key toggles between upper-case and lower-case input. This

eActivity calculations are different from RUN
•
MAT mode calculations as described below.

setting.
•You can input stop lines in an eActivity.
