Step 1 of the problem solved - Operator Error!  I finally put a real
pascal system disk in my IIGS and checked the file types.  Most were
$02 or $05.  A volume image was $00.  So I changed the .dsk file to a
type $00 file and SysUtils copied it without complaint.

Step 2 of problem.  The .dsk file is not the same as a pascal volume
image, at least as far as my system.attach drivers are expecting.  My
hunch is that the .dsk files are .do, and pascal is expecting .po.  At
least that is my working hypothesis at the moment.  Sweet16 can read
the .dsk images as pascal disks (read-only), but definately thinks
they are dos33 disks in the disk mount window.  GS/OS knows they are
pascal though.  So I am going to try to convert .do to .po on the pdos
disk, and then transfer to the pascal disk with sysutils.

Any suggestions on changing a file from .do to .po?  Or am I way off
track (no pun intended).  I got the link to the .dsk repository in the
thread on Apple Pascal on the CFFA.  The discussion was where to find
the system.attach disk and the answer was P06.DSK.  I just don't
recall the site until I go look at the message thread again.  I'll try
to post a link here as a followup msg.
