Re: st: RE: r(1000) error when running xi

[A Loumiotis <antonis.loumiotis@gmail.com>]

It's not the same but I think it is related so I modified the code
above and I now get a r(1000) error when I use the subinstr extended
macro function.

local test 0
forvalues i=1/20000 {
	local test : subinstr local test "0" "0000000000"
	local ctest : length local test
	di "`i'"
	di "`ctest'"
}

...
165169
18353
165178
18354
165187
18355
165196
system limit exceeded - see manual
r(1000);

end of do-file

r(1000);
