Dear all,

When I try to do stuff in Mata within a loop, in a do file, I receive the following error message:

--Break--
r(1);

end of do-file

--Break--
r(1);

I looked up r(1), and it says:

[P] error . . . . . . . . . . . . . . . . . . . . . . . . . Return code 1
You pressed Break. This is not considered an error.

(Of course, I don't press break while the loop is executing.)

The following very simple loop reproduces the error I get

foreach i in 1 2 {
mata:
A=1,2
A
mata clear
end
}

Any clue about what my mistake is?

All best,

Pablo Mitnik
