  R'@     "r-tick-fetch"

  ( -- x1 ) ( R: x1 x2 -- x1 x2 )

  Copy the second single-cell return stack item onto the data stack


see-also:
   ../r-quote-fetch/index.html to get the second value under the return stack

   The canonic complement would be
>  R'!
>  ( x0 -- ) ( R: x1 x2 -- x0 x2 )

usage:
   The words R@ R'@ R"@ and R! R'! R"@ can simulate
   three LOCALS living on the return stack. This is often
   enough (plus two or three items on the data stack) and
   it does not have the overhead for implicit ROOM/DROP and
   a framepointer that is needed for real locals. Plus the
   word 2R@ 2R! enables handling of a 2VALUE on the return
   stack (guidod)
