Hi all,

actually it's not a problem, I just wandering why the same code run by
ifort and f77 produced files of different size. I use
write(fileunit, *) to output free format ansic file which only
includes integer and floating numbers.

BTW: the one generated by ifort is much bigger...285M compared to
230M.....

curious about it.

Different compilers have different ideas about how many significant
digits and leading and trailing spaces to print with * format.  It's not
standardized.

If you switched to hard formatting (i10, f12.4, etc.) I expect you would
immediately get files of identical size.
