There is an even easier way to shell script this.  You can avoid
the skip= by using stdin:

for i in xaa xab xac ...
do
dd count=100 of=$i
done < $1

Or even do it "right" and completely emulate split...

We actually hacked a flag into the split(1) to do the split
in terms of blocks rather than lines.
