LCASE$ - mkilgore/QB64pe GitHub Wiki

The LCASE$ function outputs 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.

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

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

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