[I7] figuring out what row you're in

Authoring Inform 7

Is there a way to return the row number of a table you’ve just chosen? For example, I want to do something like this:

choose the row with a fruit of "banana" in the Table of Tasty Fruit;
let R be the number of the row we just chose.

Maybe try “Let X be the table row with…”
“Do something with X…”

You could try this, which I think is not appreciably slower than the “choose a row” formulation:

let R be a number; repeat with N running from 1 to the number of rows in the Table of Tasty Fruit: choose row N in the Table of Tasty Fruit; if the fruit entry is "banana": now R is N; break; if R is 0: say "Uh-oh! Banana not found! Here's where you'd usually get a run-time error."

(As far as I know there isn’t any way to get the row number directly in I7. zarf can tell you if there’s an I6 way.)

There’s a very grotty I6 way:

To decide what number is the current row: (- {-my:ct_1} -).
