st: RE: single line Mata do-while cycle
I think the problem you are having is that Mata is a compilable language, and not an interpretable language like Stata. To make loops work in Mata, you have to put them inside a function (which will be compiled after it is written), and then call the function.
I hope this helps.
Best wishes

Subject: st: single line Mata do-while cycle
I was expecting this snippet of code to work:
mata:
k=0
do k=k+1 while (k<10)
but...
: k=0
: do k=k+1 while (k<10)
'while' found where almost anything else expected
r(3000);
Breaking this into multiple lines does not help:
: do k=k+1
nothing found where 'while' expected
r(3000);
However, this one works:
do k=k+1; while (k<10)
Is that the case of "significant" semicolons per [M-2] semicolons? I
know that I sometimes need to use semicolons after -if- to indicate
absence of -else- statement in crooked branching code.
