Sorry folks. (Apologies in particular to beginners.)
The macro definition, above (gR), contains two typos:

	1. There should be a line ".." at the bottom, to end
	   the definition.
	2. An extra forward-slash appears in the ".so ..." line 
	   following the word "date".

The true definition is:

  .de gR
  .sy echo ".ds \\$1 `ls -l \n(.F | awk '{print $5, $6, $7}'`">/tmp/date\n($$
  .so /tmp/date\n($$
  .sy rm /tmp/date\n($$
