(* Multi-name declarations, in both spellings TP3 accepts.

   TP3's grammar (TPSRC7) collects a comma-separated list of NAMES, then reads
   ONE `: type' for the whole list (rdvarlst/rdvloop for VAR, prfcnt/ccomma for
   parameters), and separates parameter groups with ';'.  So all three of

      var a, b, c : integer ;        (names joined by ',')
      procedure p (x, y : integer)   (names joined by ',')
      procedure q (x : integer ; y : integer)   (groups joined by ';')

   are legal, and this fixture uses each.  The older `name : type, name : type'
   spelling is exercised too, so it keeps working.  Every variable and every
   parameter must still land on the same slot layout as if written one per
   line, which is what the printed values check. *)
