UPSHIFT( )

The UPSHIFT( ) function takes a character-string argument and returns a string in which any lowercase letters are converted to uppercase letters.

The UPSHIFT( ) function is most often used to regularize data, for example, to prevent the state abbreviation VA, Va or va from resulting in different values, if these were logically equivalent in the context of your application.

You can use the UPSHIFT( ) function in an expression where a character string is valid, in DISPLAY and PRINT statements, and in assignment statements.

Non-alphabetic or uppercase characters are not altered by UPSHIFT( ). The maximum data length of the returned character string value is 511 bytes.
