Syntax

UPCASE(argument)

Arguments

argument: specifies a character constant, variable, or expression.

Details

In a DATA step, if the UPCASE function returns a value to a variable that has not previously been assigned a length, then that variable is given the length of the argument.

The UPCASE function copies a character argument, converts all lowercase letters to uppercase letters, and returns the altered value as a result.

The results of the UPCASE function depend directly on the translation table that is in effect (see TRANTAB System Option) and indirectly on the ENCODING System Option and the LOCALE System Option in SAS National Language Support (NLS): Reference Guide.
