It suggests to me that you need to read a book on Fortran or
the Standard.  It also fails for writing to unit=6.

laptop:kargl[207] gfortran44 -o z a.f90 
a.f90:2.11:

write(*,'(I)') i
           1
Error: Nonnegative width required in format string at (1)


You can get want you by using 'write(strcounter,*) someint'
or 'write(strcounter,'(I0)') someint'.
