Example:

	GTM>DO INT^%LCASE
	String: LABEL
	Lower: label
	

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

Example:

	GTM>SET %S="Hello"
	GTM>do ^%LCASE
	GTM>zwrite
	%S="hello"	
	

This example sets the variable %S to the string "Hello" and invokes %LCASE non-interactively to convert the string.

Example:

	GTM>SET ^X="Hello"
	GTM>WRITE $$FUNC^%LCASE(^X)
	hello	
	

This example sets the variable ^X to the string "Hello" and invokes %LCASE as an extrinsic function that returns "hello" in lower case.
