Functions That Change the Case of Characters

Two old functions, UPCASE and LOWCASE, change the case of characters. As of SAS®9, a new function, PROPCASE (proper case), capitalizes the first letter of each word.

Function:	UPCASE
Purpose:	To change all letters to uppercase.
	Note: The corresponding function LOWCASE changes uppercase to lowercase.
Syntax:	UPCASE (character-value)
	character-value is any SAS character value.
	If a length has not been previously assigned, the length of the resulting variable will be the length of the argument.
