Executing Mata syntax over several dataset

[Mauricio Quinones]

Hi all. I'm trying to execute a routine over several datasets however, it stops after the first year. The syntax is,

local years 2003 2008 2015
foreach i of local years {
cd "C:/Users/Document/Data/`i'"
use "data`i'.dta"

putmata X=(x1 x2 x3)

mata
X
hh=rows(gzero)
X
hh

w=(1,2,3)
w

X1=X:*w
X1

c=rowsum(X1)

c_md=J(hh,1,0)

for (i=1; i<=rows(c); i++) {
if (c[i,1] >= 3/7) {
c_md[i,1] = 1
}
}

q = colsum(c_md)

end
clear all

Thanks in advance

Hi Mauricio.
You just missed the } parenthesis of the foreach command.
I wonder if the line hh=rows(gzero) will execute since I do not see that gzero was defined as matrix.
