No, Doug is right and you are wrong.

write(fh, "", 1)

writes an ASCII NUL onto file handle fh.  '""' (whew! got that?) resolves
to an address of a byte which contains NUL.

This is different from

write(fh, NULL, 1)
or equivalently,
write(fh, 0, 1)

which writes out the contents of address 0.  Does everyone remember what
'setf' looked like on PDP-11 systems?

&PNP,
Steve Dyer
