Program counters

If I have a program like the one shown below and i execute the program 5 times. Each time I execute the program, it will print a number 'x' to the screen. Is there any code I could write to add up the numbers which are printed to the screen each time the program is executed.

Program Sum
Implicit None
Integer :: x,n
print*,type in a value for n

x = n + 1


End Program Sum

RE: Program counters

c  Why not save the sum in a file (SUM) ?
c     program savesum      
      integer oldsum /0/ , x
      logical sumfile
      inquire (file="SUM",exist=sumfile)
      if(sumfile) then
c     A sum already exists , read it :
      read(7,*) oldsum
      rewind 7
      end if
c  ....................
c     compute x
c  ....................
      newsum = x + oldsum
      write(7,*) newsum
      close (7)
