Reading from a UNIX volume..

[Jim Witte]

Hi,

   I know, Rev probably isn't the best environment to do this particular 
thing in, but I'm just experimenting for the time being..  I want to 
write a script that will read an entire ATA volume (via USB adapter) 
into a field..  The current volume I'm working with is only 8MB, so 
this should be feasible.  The script I currently have is;

   open file "/dev/rdisk3" for binary read
   put the result into item 1 of ret
* read from file "/dev/rdisk3" for 4096 -- until EOF
   put the result into item 2 of ret
   put it into fld "rtext"
   close file "/dev/rdisk3"
   put the result into item 3 of ret

The script as written works, but if I change the starred line to 'until 
EOF' it doesn't - it gives a result code of 'eof' for the read command. 
  Does EOF do strange things if the thing you're reading from is a 
volume, and not a "real" file (whatever real means).  Is there a better 
way to read directly from a volume other doing a file read from /dev/* ?

Thanks,
Jim
