[eclipse-users] to recover the state of a variable when the predicate is used “tent_set”, library “repair"

hi....

I wanted to know like recovering the original state of a variable, after
applying to the predicate "tent_set". For example:


?- X1::1..3, X1 tent_set 2,write(X1).
        ... X1{repair:2, fd:[1..3]}


X1 =    X1{[1..3]}      -------[tent_set 2 ]----->      X1{repair:2,
fd:[1..3]}      -----[????]------>      X1{[1..3]}

bye...
