UCASE$ Function

 Action

 Returns a string expression with all letters in uppercase.

 Syntax


  UCASE$ ( stringexpression$)


 Remarks

 The  UCASE$ function takes a string variable, string constant, or string
 expression as its single argument.  UCASE$ works with both variable- and
 fixed-length strings.

  UCASE$ and  LCASE$ are helpful in making string comparisons that are not
 case-sensitive.

  LCASE$

 Example

 This example contains a  FUNCTION procedure, YesQues, that returns a Boolean
 value depending on how the user responds. The procedure uses  UCASE$ to make
 a non-

  case-sensitive test of the user's response.

 DEFINT A-Z
 FUNCTION YesQues(Prompt$,Row,Col) STATIC
 OldRow=CSRLIN
 OldCol=POS(0)
 ' Print prompt at Row, Col.
 LOCATE Row,Col . PRINT Prompt$ "(Y-N).";
 DO
 ' Get the user to press a key.
 DO
 Resp$=INKEY$
 LOOP WHILE Resp$=""
 Resp$=UCASE$(Resp$)
 ' Test to see if it's yes or no.
 IF Resp$="Y" OR Resp$="N" THEN
 EXIT DO
 ELSE
 BEEP
 END IF
 LOOP
 PRINT Resp$;' Print the response on the line.
 LOCATE OldRow,OldCol' Move the cursor back to the old position.
 YesQues=(Resp$="Y")' Return a Boolean value.
 END FUNCTION

 DO
 LOOP WHILE NOT YesQues("Do you know the frequency?",12,5)
