The second reference I can supply as

        tip on using forvalues to loop over numbers

but quite what it has to do with your problem I cannot say. I cannot imagine any connection. 

We need _precise_ detail:

1. What exactly is the constraint and how did you specify it? 

2. What exactly did you type to get a bivariate probit model? 

3. Precisely which email are you referring to? (It will have a URL.)

I am running a bivariate probit with a constraint. The constraint is
built following a previous loop. If the condition holds it creates the
constraint for the arthrho and then I use the constraint in the
bivariate probit. Once the bivariate probit is running I got the note
(note:constraint number 1 caused error (303) when the bivariate is
fitting equation 1 and equation 2. In any case the bivariate continues
and give me the final outcome. I am not sure whether is an actual
error or if it was just a comment to take into account.

In past stata lists someone got that error and someone addressed him
to the Stata Journal, STATA TIP 85 written by professor Cox. I have
read the article and it is most about looping among integers. actually
my loop is on several iterations that are still I do not
know what my problem is.
