Richard is right. If I
print "('DIR hex = ', z8,', DIR decimal =', f9.6)", idir, idir
then it works. I got the hex value I was trying to print by using
print "('DIR hex = ', z8,', DIR decimal =', f9.6)", dir, dir
in a different program, compiled with the same compiler, which is why
I expected to be able to write a REAL using Z8 format. (I should have
been suspicious when reading a REAL didn't work.) It makes one wonder
why it worked in one place and not the other.
Best regards,
Van
