I really appreciate knowing that both Scott Miller and Bill Baker (and
probably many other persons, I assume) have used the DISPLAY command in
ARC/INFO to output to a ASCII .txt file with no problem.  When I was
converting files from ARC/INFO to GRASS, I was getting a BAD WRITE error.  I
was planning to call the ARC people, but I got around the problem by using
the REPORT command. 

Just to check the procedure again, I just used the DISPLAY command on one of
my files.  The following is the error that I get if I use the DISPLAY command
in INFO to create the ASCII .txt file for GRASS. 

AN EXAMPLE OF THE ERROR:

I do have enough space and write permission in my /home/sayeed directory.  I
talked to the system administrator, but he was clueless.  I have been using
ARC/INFO 7.0.2 and UNIX system on IBM RS/6000.  Has anyone else got the same
type of problem? If anybody has any clue, please let me know. 

Thanks in advance.
