When execution reaches an INPUT statement, the program pauses and waits for the user
to enter data from the keyboard while showing a prompting message specified by
"prompt".
After typing data, the user must press the ENT key. Then, the INPUT statement assigns
the typed data to variable.
• "prompt" is a prompting message to be displayed on the LCD.
• The semicolon (;) or comma (,) after "prompt " has the following meaning:
If "prompt " is followed by a semicolon, the INPUT statement displays the prompting
message followed by a question mark and a space.
INPUT "data=";a$
data=?
If "prompt" is followed by a comma, the statement displays the prompting message
but no question mark or space is appended to the prompting message.
INPUT "data=",a$
data=
