Re: st: RE: forvalues gives "numlist has too many elements" error

[Pablo Mitnik <pmitnik@ssc.wisc.edu>]

Problem solved. It was not as I explained it at first. The problem was 
with foreach. When I replaced it by forval, I still got the same message 
error, but it was
because there was another foreach further down in the code, which I had 
forgotten about.

Thanks much Nick for pointing me towards what the real problem was (and 
for the suggestion re nullmat).
Pablo.
