Example:

	GTM>DO INT^%UCASE
	String: test
	Upper: TEST
	

This example invokes %UCASE in interactive mode using INT^%UCASE. %UCASE prompts for a string that it converts to all upper case.

Example:

	GTM>SET ^X="hello"
	GTM>WRITE $$FUNC^%UCASE(^X)
	HELLO
	

This example sets the variable X to the string "hello" and invokes %UCASE as an extrinsic function that returns "HELLO" in upper case.
