Checking User Input
If you know that the player's input must be above or below a certain number of characters, you can (in some occasions) use LEN$() to check if the player has entered a valid response.
DIM A AS STRING
INPUT "Type red or blue", A
IF LEN$(A) < 3 OR LEN$(A) > 4 THEN PRINT "You didn't type red or blue."
