Hi again.

I have a a CC3 with OS9 Lvl 2 and I noticed a strange thing when
iniz'ing the /r0 ram disk.

If I type this command frmo the shell prompt :

	os9>iniz /r0
	os9>mfree
	... 240k ...

And do a mfree I end up with 240k of free memory.  But if I place the
above command in a shell script and execute the script from the shell I
end up with 232k of free memory.  Why?

	os9>list initram
	iniz /r0

	os9>initram
	os9>mfree
	... 232k ...

Know here may be a clue!  If after performing the iniz I do this :

	os9>iniz r0
	os9>deiniz r0
	os9>mfree
	... 432k ...

But if I execute the shell script I cannot deiniz the ram disk.  Is
there some phantom process which is holding a path open to the ram
disk?

	os9>initram
	os9>deiniz r0
	os9>mfree
	... 232k ...

Would anyone else like to try this out.
