Printing certain values from a Fortran DO loop

Printing certain values from a Fortran DO loop

Printing certain values from a Fortran DO loop

(OP)
I've written a program in Fortran which has a do loop of the form

do i=0,20000

(operations)

end do

I want the program to print the values of the do loop, but only want it to print every 100th value of i (i.e. i=100,200,300,400...20000), can anyone suggest a way to do this?

CODE

do i = 0, 20000, 100
...
end do

RE: Printing certain values from a Fortran DO loop

(OP)
Yeah, that would be fine expect the program needs to write all of the intermediate values do the screen. I've found the answer though, adding

   if (mod(i,100) .eq. 0) then
      write(unit=7,fmt="(3e15.7)")  variable1, v2, v3
   end if

at the end of the DO loop, where 7 is an output file.
