LCASE$

The LCASE$ function returns an all-lowercase version of a STRING.

result$ = LCASE$(text$)

• Normally used to guarantee that user input is not capitalized.
• Does not affect non-alphabetical characters.

The following code guarantees that all user letter entries will be lower case:

PRINT "Do you want to continue? (y/n)"

DO
    K$ = LCASE$(INKEY$)
LOOP UNTIL K$ = "y" OR K$ = "n"

• UCASE$ (upper case)
• INKEY$
• INPUT$
