Abdel was quite correct to leave out an -end- statement. His example was a series of separate invocations of Mata.--

Thanks for your answer -- but observe you left the end statement out. I
want to get out of Mata and continue doing stuff in the loop. When you
add the end command, the error I described is generated.

My guess is that you have to respect much more the fact that Stata and Mata are different languages. I don't think you can mix them quite like this.
Something like
foreach ... {
...
myprog ...
...
}
where -myprog- is a Stata program that calls Mata is more likely to succeed.
As your real problem is different, further advice may wait upon details.

When I try to do stuff in Mata within a loop, in a do file, I receive
Returnthe following error message:
--Break--
r(1);
end of do-file
--Break--
r(1);
I looked up r(1), and it says:
[P] error . . . . . . . . . . . . . . . . . . . . . . . . .
*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?
