Subject:      %fmtpath macro failes.

%fmtpath looks like a very useful macro, although in v8.2 it fails

%do i=1 %to %words(&cats);
  %let cat=%scan(&cats,&i,%str( ));
  %if not %index(&cat,.) %then %let cat=&cat..FORMATS;
  %let catlist=&catlist &cat;
%end;

WARNING: Apparent invocation of macro WORDS not resolved.
SYMBOLGEN:  Macro variable CATS resolves to ACTMOD LIBRARY WORK
ERROR: Required operator not found in expression: %WORDS(&CATS)
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro FMTPATH will stop executing.
435   %fmtpath

I did not find %words in the macro language dictionary of version 9.1.3.
