" Last Change:  2012 Apr 20
"               Corrected bug causing some keywords to appear as strings instead
"               18 Jul 2008 by Paulo Tanimoto <ptanimoto@gmail.com>
"               Fixed comments with * taking multiple lines.
"               Fixed highlighting of macro keywords.
"               Added words to cases that didn't fit anywhere.
"             	02 Jun 2003
"		Added highlighting for additional keywords and such;
"		Attempted to match SAS default syntax colors;
"		Changed syncing so it doesn't lose colors on large blocks;
"		Much thanks to Bob Heckel for knowledgeable tweaking.
