@ ( a-addr – w ) core “fetch”
w is the cell stored at a_addr.
! ( w a-addr – ) core “store”
Store w into the cell at a-addr.
+! ( n a-addr – ) core “plus-store”
Add n to the cell at a-addr.
!@ ( w1 a-addr – w2 ) gforth-experimental “store-fetch”
Fetch w2 from a_addr, then store w1 there.
There is also atomic!@ (see Hardware operations for multi-tasking).
+!@ ( u1 a-addr – u2 ) gforth-experimental “plus-store-fetch”

2@ ( a-addr – w1 w2 ) core “two-fetch”
w2 is the content of the cell stored at a-addr, w1 is the content of the next cell.
2! ( w1 w2 a-addr – ) core “two-store”
