Re: GS/OS: looking for info on VCB and FCB (***Full post***)

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

OK, I've scanned the "GS/OS System Service Calls ERS" document (plus a 
couple of other documents it references - although they're not a lot of use 
in reality). There's 48 pages in a PDF file.

http://www.peter-watson.net/misc/GSOS_System_Service_ERS.pdf
or
http://www.peter-watson.net/misc/GSOS_System_Service_ERS.zip

The zip file is a little smaller (918K vs 973K) in case someone is still on 
a low net connection.
