(See the best response by LordAndrew.)
Code:
mob
    npc
        var
            disp = 45
            attack = 90
            flee = 40
            greet = ""
            detectplayer = 0
        proc
            var
                roll = 0
            GreetRoll(mob/npc/M)
                switch
                    if(M.disp <= 25 && M.detectplayer == 1)
                        roll = rand(1,3)
                        switch 
                            if(roll == 1)
                                M.greet = "What are you doing around here? Get lost!"
                            if(roll == 2)
                                M.greet = "You know I hate you, and you know I can't tand your presence. Go away."
                        
                            if(roll == 3)
                                M.greet = "I hate you so much..."


Problem description:

I was working on the AI for a game I'm working on. I haven't used DM in MONTHS, so I have pretty much forgotten everything. The compiling results are:


if(M.disp <= 25 && M.detectplayer == 1) - missing expression

if(roll == 1) - missing expression

Best response
switch()

switch(roll)
    if(1) // things
    if(2) // other things
    // etc

Dammit, can't believe I forgot that the switch forgot (), thanks LordAndrew. :) Also, since I'm detecting the disp and detectplayer vars, should I use those in the switch at the top?

EDIT: Nevermind , turns out the switch statement was useless, and caused lots of errors, this worked:

mob
    npc
        var
            disp = 45
            attack = 90
            flee = 40
            greet = ""
            detectplayer = 0
        proc
            GreetRoll(mob/npc/M)
                var
                    roll = 0
                if(M.disp >= 0 && M.disp <= 30)
                    roll = rand(1,3)
                    if(roll == 1)
                        M.greet = "What are you doing around here? Get lost!"
                    if(roll == 2)
                        M.greet = "You know I hate you, and you know I can't tand your presence. Go away."                      
                    if(roll == 3)
                        M.greet = "I hate you so much..."
                else if(M.disp >= 31 && M.disp <= 44)
                    roll = rand(1,3)
                    if(roll == 1)
                        M.greet = "Oh, it's *you*..."
                    if(roll == 2)
                        M.greet = "Don't bother me, and their won't be trouble."                        
                    if(roll == 3)

                    roll = rand(1,3)

Instead of your roll, you can simply pick() a random item from a list of messages. Also, you can still use switch() to see if a variable is within a set of bounds.

switch(M.disp)
    if(0 to 10) m.greet = pick("I hate you.", "You suck.", "Go away.")

pick never works when I use it, if I do, it never uses a RANDOM value, just the same one over & over.

From the DM Reference


Also, to pick a value randomly from a list, simply pass the list as the sole argument into pick(). In this case, there is no provision for weighting the probabilities. All items in the list are equally likely.
