	I'm trying to do some GEM programming and I'm having a few problems.
Does anyone else have any experience they can share in doing this?

	Specifically, I'm trying to write metafiles.  The problems I'm 
coming across involves v_opnwk(), v_clswk(), v_opnvwk(), and v_clsvwk().  
Of course I assign workin_in[0] = 31 for metafiles.  

	This is what happens.  When I compile and run the program with 
v_opnvwk(), the handle comes back zero and it crashes when I try to call
v_clsvwk().  When I instead use v_opnwk(), it writes a 68 byte file to disk
called GEMFILE.GEM and then crashes.  I get 2 bombs and it does not come
back from that command.  

	ABACUS GEM Programmer's Reference mentions that v_opnwk() does not
work on the ST and tends to crash.  Is there a reason for this, or is it a
case of I don't know what I'm doing?  

	Thanks for any help.
