That is implementation dependent. They may also do such things as store
a byte length at the address, or even store a value *before* the address
passed. They may not even have a length you can use at all, if it's an
old Fortran. I would suggest you do this:

char foo[80];

main()
{
	int i;

	fortest();

	for(i = 0; i < 80; i++)
		printf("%03o", foo[i]);
}

       SUBROUTINE FORTEST
       CHARACTER*80 BAR
       COMMON /FOO/ BAR
       BAR = 'TEST STRING'
       END

Then get your ascii table and examine the output.
