MMYYxw is a format.  You need an informat (which doesn't exist).

Read the data as char and convert it using INPUT, SUBSTR, and the YYMMNw
informat.

We have odd dates with 2 digit years.  Sometimes they are in the form of
'0702' which I use YYMMn4. to convert to 200702 using YYMMn6.
sometimes they are '0376' which should convert to 197603 using MMYYn4.
But SAS complains that there is no such informat. It's documented in the
SAS on-line doc, in Rick Aster's book, and in Derek Morgan's book.  What
gives?  SAS 9.1.3 Service pack 4 on windows.

MMYY4 = put(input(Index_base_date,MMYYN4.),MMYYN4.);
