The UCASE$ function returns an all-uppercase version of a STRING.
result$ = UCASE$(text$)
- Used to guarantee that all alphabetical characters in a STRING are capitalized.
- Does not affect non-alphabetical characters.
The following code guarantees that all letter key entries are capitalized:
PRINT "Do you want to continue? (y/n)" DO K$ = UCASE$(INKEY$) LOOP UNTIL K$ = "Y" OR K$ = "N"
