Removing MacOS forks from ProDOS 8 files

[walt@hugh.physics.ucsb.edu (Walter Polkosnik)]

I have a IIgs I'm trying to transfer some files to. I don't have a modem or
null cable, all I've got is a ProDOS 8 boot disk. I've been trying to use
the MacOS capability to read/write ProDOS 8 3.5" disks, but I've hit the
problem of the Mac adding resource forks to files that makes them
unreadable under ProDOS 8. I've tried ProTYPE, and it successfully decodes
BinSCII files (I successfuly used it to get Shrinkit 3.4 running).

ProTYPE also purports to automatically remove resource forks from .SHK
files, but it doesn't seem to be successful in that aspect. I've downloaded
some .shk's, but Shrinkit won't read the file because it's still forked
(even though I ran it through ProTYPE). I ran files through ProTYPE both
before and after dragging to floppy and neither seemed to work. 

Am I doing something wrong? Do I need to change the filetype on the Mac to
TEXT or BINA for ProTYPE to work correctly? Does ProTYPE actually do what
it purports to? If it doesn't, what other program can I use to remove
resource forks? 

Thanks.
