Question

So sample loop:

do i=1,1
    print *,i
enddo
print *,i

gives me 2 as the final value of i. How can I set up Intel Fortran for Visual Studio on Windows to give me a final value of 1 for i?

Answer 1

You can’t, because that’s how DO works; it stops when the control variable exceeds the limit.

In general, in pretty much any language with a FOR/DO counting loop, you should only use the loop control variable inside the loop body, and treat it as undefined elsewhere, even if you can’t actually limit its scope to the body.

In your case, I would use a different variable to keep track of the actual last value of i in any iteration:

lasti = 0
do i=1,1
   print *,i
   lasti = i
enddo
print *,lasti
