I don't know if it is running correctly, but your code does run for
me. With a data set already open, I wind up with 2 vars, _MLtu1 and
_MLw1, whose values all equal 1. I suggest you make sure your
Stata is entirely up to date. If you really are on 10.0, whatever
your problem is may have been fixed in 10.1. Use the -update all-
command and follow the instructions.

Dear Nick,
I'll try to be more clear.
following my program:
program define myprogram
version 10.0
args lnf a b c e
tempvar sigma mc ma msigma mb
quietly gen double `sigma'=0.5*`e'
quietly gen double `mc'=1-`c'
quietly gen double `ma'=1-`a'
quietly gen double `msigma'=1-`e'
quietly gen double `mb'=1-`b'
quietly replace
`lnf'=ln((`a')*(`b')*((((`mc')*(`sigma')+(`m'))^alfa)*(((`mc')*(`sigma'))^s)*(((`mc)*(`msigma'))^n))+
(`a')*(`mb)*((((`mc') *(`sigma'))^b)*(((`mc') *(`sigma')
end
Everything is fine, but when I type:
ml model lf myprogram (a:) (b:) (c:) (e:)
Stata tells me that is invalid syntax.
What's wrong?
Thanks
