!8 causes command number 8 to be retrieved from the CI's redo stack and
substituted into the command line.  This always happens -- even if !8 is
preceeded by COMMENT.   The CI performs "string substitution" before knowing
what the command name is.

I can't figure out why you get a divide by zero error!  Maybe knowing
what command 8 is will help?  (If command 8 does not exist in the redo
stack you should just get this warning:
   "Invalid numeric index into the redo stack. (CIWARN 8164)"
