Thanks! I made the change, recompiled and tested it, and it works fine -
well except for one thing: whether or not the room's long description is
printed depends on what the player's brief mode is toggled to. I expected
this, and decided to look at the code for look_at_room (in
act.informative.c). Here's what the part of look_at_room dealing with
printing the long room description looks like:
if (!PRF_FLAGGED(ch, PRF_BRIEF) || ignore_brief ||
ROOM_FLAGGED(ch->in_room, ROOM_DEATH))
send_to_char(world[ch->in_room].description, ch);
(ignore_brief contains the value of the second argument to look_at_room)
Now, I'm wondering if there's a logic error in there, or if look_at_room
just wasn't intended to be able to be forced to skip the long room desc.
The reason for this is that (from what I can tell) in order for the long
desc to be skipped, the following must be met:
1) the player is in brief mode
2) ignore_brief is equal to 0
3) the player is not in a deathtrap room? (this doesn't matter, since you
want it to print the long description anyways probably)
As you can see, regardless of the value of ignore_brief, look_at_room will
still show the long desc if the player is not in brief mode.
SO, (sorry for being so wordy) what would be the best way to work around
this so that, when the user hits ENTER at the command prompt, the game
does look_in_room WITHOUT printing the long room desc? Probably the safest
way (to keep other code from breaking/misbehaving) that I can think of is
to make a copy of look_in_room, rename the copy, and take out the first
condition in the if() statement above (then have command_interpreter()
call the new function). Does this sound like the best way to go, or is
there a better way? Thanks!

First of all, I DID look around in the code for at least a half an hour,
with little success. As I said, I'm new to the CircleMUD code (and MUD
coding in general). Currently I do not know what most of the "important
frequently used functions" are (nor their locations), although I intend to
find out (by diving in - not by bugging the helpful people on this list =)
Is there some sort of doc/FAQ that I can read to find out more about the
current organization of the CircleMUD code?

I don't see how it would be very obvious, unless you already know what
you're looking for (which I didn't). Perhaps you'd like to write some docs
on it if there aren't any already? ;)

I'm not afraid to get my hands dirty! In fact, I very much look forward to
it (actually, I am already in the process of experimenting =)
Thanks again for the help everybody!
