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);
