Looks nice Udo, but I'm not looking for a UNIX file to run with an
emulator. 
I need something that will run on a *REAL* Z-80 with CP/M.  I don't even 
think my machine can uncompress/whatever a *.tgz file anyway.

I get the block thing now.  But it still seems pretty weird/foolish to 
simply abandon the OS's filesystem for something as primitive as disk 
blocks.  The enhancement you made seems to me to be the reasonable way to 
approach it - still use blocks at the user lever, but have those blocks go

into a file - is that it?
