Thanks, Clem. Now I'm getting somewhere!<br>
<br>
I converted to a tap file (lo and behold, I wrote a perl script that
did this for the silly thing 2 years ago) and ran it. Then attached
the tap to simh and in v7:<br>
<br>
<tt># tar xvfb /dev/rmt0</tt><tt><br>
</tt><tt>Invalid blocksize. (Max 20)</tt><tt><br>
</tt><br>
hmm... that doesn't sound good, let's try it another way:<br>
<br>
<tt># tar xv0</tt><tt><br>
</tt><tt>tar: ashell/ - cannot create</tt><tt><br>
</tt><tt>x ashell/cont.a, 114488 bytes, 224 tape blocks</tt><tt><br>
</tt><tt>x ashell/READ_ME, 825 bytes, 2 tape blocks</tt><tt><br>
# ls -ld ashell<br>
drwxrwxr-x 2 root 64 Dec 31 22:18 ashell<br>
# ls ashell<br>
READ_ME<br>
cont.a<br>
# find . -name "more*" -a -print<br>
# <br>
</tt>...<br>
<br>
It's coming back to me now, but oh so slowly, why is it complaining
about cannot create all the while creating the folder? Also, darn! I
was hoping more would be in there somewhere. Anybody know where the
more or less pager source code might be for v7?<br>
<br>
Thanks,<br>
