To remove (way - direction) exit from (place - room): (- I7_ChangeExit({place},{way},nothing); -).
Usage:
Remove the north exit from Home.
Understand "your" as a thing when the item described is held by the person asked.

To decide if (snip - snippet) is identical to (capricorn - topic): (- (I7_match_snippet = I7_IdenticalTopic({capricorn},{snip})) -).
To decide if (snip - snippet) refers to (capricorn - topic): (- (I7_match_snippet = I7_RefersTopic({capricorn},{snip})) -).
To decide which object is the matched thing: (- I7_TopicNoun() -).
Usage:
if the topic understood refers to "[any thing]", say "You mentioned [the matched thing]." if the topic understood is identical to "[any person] is nice", say "You seem to like [the matched thing]."
To decide which snippet is verb word: (- (100*verb_wordnum+1) -).
To make the location visible: (- FindVisibilityLevels(); if (location ~= thedark && visibility_ceiling == location) PlaceInScope(location); -).Usage:
After deciding the scope of the player when examining: make the location visible. Instead of examining the location, try looking.
Removed; functionality now exists in Inform.
To label (n - number): (- .marked_spot{n}; -).
To jump to label (n - number): (- jump marked_spot{n}; -).
Usage:
Instead of jumping: say "This is a test."; jump to label 42; say "This should not appear."; label 42; say "End of test."
To say perform (ph - phrase): (- if (0==0) {ph} -).
Usage:
Home is a room. A hamburger is here. Mary is a woman in home. Mary carries a flower. Instead of asking Mary about a topic listed in the table of Mary talk, say response entry. Table of Mary talk topic response "food" "'I like food.'[paragraph break][perform try mary trying taking the hamburger]" "flowers" "[if mary carries the flower]'Here, have a flower.'[paragraph break] [perform try mary trying dropping the flower] [otherwise]'I'm sorry, I have no more flowers.'[paragraph break][end if]" "exits" "'I have to go now.' And with that, she vanishes.[perform remove mary from play][paragraph break]" Test me with "ask mary about food / ask mary about flowers / ask mary about flowers / ask mary about exits".
Removed; can use indexed text instead.
This can be done more easily now using indexed text.

To start buffering text: (- StartTextBuffer(); -).
To stop buffering text: (- StopTextBuffer(); -).
To display buffer in status line: (- PrintStatusBuffer(); -).
To output spacer: (- StatusSpacer(); -).
Rule for constructing the status line:
start buffering text;
if the status line description of the location is "", say "I'm in a [location]";
otherwise say status line description of the location;
say "[line break]Obvious exits: [obvious exits][line break]Visible items: [notable things][line break]";
output spacer.
stop buffering text;
display buffer in status line.
To say obvious exits:
repeat with way running through directions begin;
let neighbor be the room way from location;
if neighbor is a room, say "[way capitalized] ";
end repeat;
To say (way - direction) capitalized:
if way is north, say "NORTH";
if way is northwest, say "NORTHWEST";
if way is northeast, say "NORTHEAST";
if way is west, say "WEST";
if way is east, say "EAST";
if way is south, say "SOUTH";
if way is southeast, say "SOUTHEAST";
if way is southwest, say "SOUTHWEST";
if way is up, say "UP";
if way is down, say "DOWN";
if way is inside, say "IN";
if way is outside, say "OUT".
To say notable things:
let count be the number of notable things;
if count > 0 begin;
let i be 1;
repeat with item running through notable things begin;
say "[item]";
if i < count, say ", ";
increase i by 1;
end repeat;
otherwise;
say "None";
end if.
Definition: a thing is notable if it is visible and it is not the player and it is in location.
A room has some text called status line description. The status line description of a room is usually "".
Usage:
Ghost Town is a room. A hat and a shovel are here. Saloon is north of Ghost Town. Brothel is south of Ghost Town. The status line description of the brothel is "I'm in a seedy looking brothel".
Removed; no longer functional. See my extension Consolidated Multiple Actions.
To decide if testing is in progress: (- (TestCheck()) -). To decide if testing is not in progress: (- (~~TestCheck()) -). Include (- [ TestCheck ; if (test_stack-->2 > 1) rtrue; rfalse; ]; -).
The last command is an indexed text that varies. The parser error flag is a truth state that varies. The parser error flag is false. Rule for printing a parser error when the parser error is only understood as far as and the player's command matches the text "with": change the last command to the player's command; change the parser error flag to true; let n be indexed text; let n be the player's command; replace the regular expression ".* with (.*)" in n with "with \1"; say "(ignoring the unnecessary words '[n]')[line break]"; replace the regular expression "with .*" in the last command with "". Rule for reading a command when the parser error flag is true: change the parser error flag to false; change the text of the player's command to the last command.Usage:
The cave is a room. The troll is a man in the cave. The player carries a sword. The chest is a locked lockable container in the cave. Test me with "attack troll with sword / unlock chest with sword / attack troll as a test".
