The issue reported by Daniel has also troubled me many
times. I think the problem is that Mata waits for -else-
if the -if- construct is used interactively (i.e. outside
a function). Here's a little illustration:
. mata:
: if (1==1) 1
> end
unexpected end of line
(0 lines skipped)
r(3000);
. mata:
: if (1==1) 1
> else 0
1
: end
I see no reason why using -if- without -else- should work
within a function but not in interactive mode. My suggestion
would be that the problem be fixed by Stata Corp.
