3997.0. "Who or what is gdos ? " by MAJORS::BASSETT (John Bassett. UKLEG DTN 7830-4017) Wed Aug 08 1990 08:49

Hi all,

	I'm currently experiencing some strange behaviour on my A500. Whenever
I use the grep utility supplied with lattice C V5 it searches all the files 
correctly and then prints the message 

	can't find file(s): gdos

Also after using Mostra to view a SHAM image the informational message printed
always has 'gdos' appended to it. There have also been other occasions when 
using various software that this *!$#@! gdos has been appended to error 
messages.

All my software still seems to function correctly it's just annoying to keep 
getting this message. Any ideas as to what gdos is and why it has suddenly
started appearing all over the place ?

thanks,
John.

Well, I don't know why that message is there, but I would get my copy of
NewZAP out and fig it to say ADOS, not gdos :-)

3997.2More information please!SDOGUS::WILLIAMSTOPGUNWed Aug 08 1990 18:385
    I don't know either.  But I'll try using my lattice C V5 grep and
    see what I get.  Got some more information on what you are configured
    as?  E.g.  expansion disk, memory, etc.?

3997.3Some more info......MAJORS::BASSETTJohn Bassett. UKLEG DTN 7830-4017Thu Aug 09 1990 04:2021
my configuration :-
	
	A500 + 1/2 Mb expansion
	A590 + 2Mb

Usually I have the following software running : ARP 1.3, Mackie (POPCLI 
replacement). 

As an example of the problem if I search all .c files using

grep garbage #?.c

then I get the message given in .0 If I then create an empty file called gdos
in the current directory everything proceeds normally and no message is 
produced. 

BTW As I never use workbench I have deleted most of the .info files 
from the system disk. Could this be causing the problem ?

thanks,
John.

    Re: *
    
    You have the classic A590/A2091 "Location Zero Bug". This is caused by
    improper programmed applications that read address zero (instead of
    using a NULL pointer) which got changed from zero to point to string
    with the contents (you guessed it) "gdos" by a debugging version of the
    FastFilesystem that got shipped with the early CBM controllers.
    To get rid of this, update the FastFileSystem on your RigidDiskBlock
    with the 1.3.2 release. Since I don't own a 2091 or 590 I can't tell
    you exactly how to accomplish this, but it has been descriped over and
    over again on UseNet.
