Tom's code is correct; the = is required: scalar ng = 6 forvalues i=1/`=ng' { di `i' } 1 2 3 4 5 6 However, the code Nicola claimed to work, cannot: forvalues 1/6 { di `i' } invalid syntax r(198); Since the problem is not the forvalues loop, it must be the code within the loop. I suggest setting -trace on- to see where it blows out and/or manually performing each matrix line to find the syntax problem. Tom ----------------------------------- Thomas J.
