Everything in CMC is one of five kinds of thing. what(x) tells you which:

oga what(3)          ugg number
oga what("hi")       ugg text
oga what(gronk)      ugg truth
oga what(plop)       ugg plop
oga what(snorf())    ugg pile

number

Whole numbers and decimals. Everything you expect works:

oga 7, 3.5, 0 - 2
oga 2 + 3 * 4        ugg 14, times goes first
oga (2 + 3) * 4      ugg 20, parentheses are your friend

Division gives a whole number when it fits:

oga 4 / 2            ugg 2
oga 5 / 2            ugg 2.5

Numbers print naturally: 2.0 shows as 2.

text (goop)

Text is letters, numbers, and symbols inside quotes:

grunk name = "Ugg"
grunk empty = ""
oga name + " the cave kid"
oga nom(name)                  ugg 3, how many letters
oga name[0]                    ugg U
oga shout(name), whisper("HEY") ugg UGG hey

Text cannot be glued directly to numbers with +. Use goop:

oga "I am " + goop(7) + " years old"

truth (gronk / nork)

Checks give back gronk (yes) or nork (no):

grunk hungry = gronk
oga hungry                ugg gronk
oga not hungry            ugg nork
oga 3 > 5                 ugg nork

and, or, and not work the way you expect, and stop early when they can:

binga hungry and rocks > 0
    oga "eat a rock"
unga

plop

plop means nothing at all:

• A clump without ork gives back plop
• A fresh box with nothing in it holds plop
• plop prints as the word plop

clump shout_if_loud(word)
    binga nom(word) > 4
        ork shout(word)
    unga
    ork plop
unga

oga shout_if_loud("hi")        ugg plop
oga shout_if_loud("booga")     ugg BOOGA

The same word has a doing version: plop(pile, thing) adds to a pile. Read plop(pile, thing) for that one.

pile (snorf)

A pile is an ordered list that can grow and shrink:

grunk bag = snorf("apple", "rock")
plop(bag, "banana")
oga bag            ugg [apple, rock, banana]
oga nom(bag)       ugg 3

Piles can hold any mix of kinds, even other piles:

grunk treasure = snorf(1, "gold", gronk, snorf("deep", "pile"))
oga treasure

[1, gold, gronk, [deep, pile]]

What counts as gronk in a check?

This means binga rocks works and means "does rocks hold a non-zero number?"

Comparing unlike things

== and != never crash: different kinds are simply not equal.

oga 1 == "1"        ugg nork
oga gronk == 1      ugg nork
oga plop == plop    ugg gronk

But < and > need two numbers or two texts:

oga "apple" < "banana"    ugg gronk (alphabetical)
oga 3 < "four"            ugg OOGA! with a hint
