Hi,
some time ago I reported on statalist that the 
-:word of- extended macro function appears to 
truncate long words to 503 characters. See: 

 http://www.stata.com/statalist/archive/2005-11/msg00643.html

This limit of the -:word of- function causes a 
problem in -estout-. The problem has been 
reported by Radu Ban, see 

 http://www.stata.com/statalist/archive/2005-11/msg00620.html

And my reply:

 http://www.stata.com/statalist/archive/2005-11/msg00644.html

-estout- may break if you try to create a table of 
a *large* number of stored estimates (say 100 or 
more). (-estout- uses local macros to build a 
logical representation of the basic structure of 
the table. If the table rows are getting very long, 
-estout- may hit the 503 character limit of the 
-:word of- function.)
 
Here is what Stata Technical Support had to say 
about the problem:

"It turns out that the -:word of- extended macro 
function pulls 'tokens' off of the string as words, 
and Stata's internal parser has a limit of 503 
characters for a 'token'. StataCorp is looking into 
changing the -:word of- extended macro function to 
not be affected by this limit."

-estout- will be fixed once the -:word of- extended 
macro function is changed.
