David,
 
SUDAAN only reads SAS 6.04 datasets.  It will not read SAS format catalogs.
 Therefore, the cntlout option of proc format must be used to generate a SAS
data set containing the format information.  The data set must be version
6.04  (notice the 604 engine specified on the libname statement).  The
formats can be specified in the SUDAAN program or in a SAS data step.  Be
careful when using formats; they cannot be used to collapse groups i.e.
     value ages
          1-10 = 1
          11-20 =2;
will explode in SUDAAN.    SAS and SUDAAN example progams follow.
