Re: GS/OS: looking for info on VCB and FCB

["Peter Watson" <paw77@N_O_hotmail_S_P_A_M.com>]

The preliminary documentation describes some of these calls.
I've marked the ones that appear in the "GS/OS System Service Calls ERS" 
document I have.
- Some of the calls are only minimally documented.
- There is no guarantee the calls function the same way in the release 
versions of GS/OS.

I'll see if I can get a scan of the section of the manual - it's certainly 
too long to type in!  :-)
