Oh, there is a way. I should have checked the docs first.
This works:
The Kitchen is a room.
The player carries a rock.
The player carries a stone.
The player carries a pebble.
Include (-
Global third;
-) after "ICL Commands" in "Output.i6t".
The third noun is an object that varies.
The third noun variable translates into I6 as "third".
Include(-
[ ThirdNoun x;
x = ParseToken(ELEMENTARY_TT, NOUN_TOKEN);
if (x == GPR_FAIL or GPR_REPARSE) return x;
third = x; return GPR_PREPOSITION;
];
-).
The Understand token third-noun translates into I6 as "ThirdNoun".
Combining it with is an action applying to two things.
Understand "combine [something] with [something] with [third-noun]" as combining it with.
Report combining it with:
say "Combined [the noun] with [the second noun] with [the third noun]."
Test me with "combine rock with stone with pebble".Note that the action is defined as “applying to two things”. I7 doesn’t understand that there’s a third noun, so you have to write it that way.
