Rocket Man

Using case changes on any text produced by a "to say…" phrase.

We can now change the case of any text produced by a "to say…" phrase. This is often useful when we would like to make use of a standard say phrase in some new context. Say, for instance, that we would like to "[is-are the list…]" in a context that needs the first letter to be capitalized.

We could write a new say phrase, such as "to say is-are the list of (N - a description of objects) in sentence capitalization"; but there is an easier way, and that is to set a text variable to the output of the to say phrase, and then print that text in the case of our choice.

For example:

Play/modify in Borogove

Play in Quixe

"Rocket Man"

Instead of going somewhere from the spaceport when the player carries something:

let N be "[is-are the list of things carried by the player] really suitable gear to take to the moon?" in sentence case;

say "[N][paragraph break]".

The Spaceport is a room. North of the Spaceport is the Rocket Launch Pad. The player carries a stuffed bear, a chocolate cookie, and a book.

The description of the book is "It is entitled [italic type]Why Not To Take [sentence cased inventory] To The Moon[roman type]."

To say sentence cased inventory:

let N be "[a list of things carried by the player]" in title case;

say "[N]".

Test me with "n / x book".
