You actually do not need to enbed each record in a block. For each
SORT call you can use the /skip refinement to define the length of
the record. This way you can do the SORT by name like this:
sort/skip citas 4
and by email:
sort/compare/skip citas func [x y] [ (second x) < (second y) ] 4
This is not always a better solution, just flatter. It depends on all
the functionality that you wish to implement which way you want to do
it.
One last note is that if you joined your date and time fields to a
REBOL date value, you could also sort by date and time at once. With
the fields split, SORTing by date and time together will be difficult.
