Note: a word is considered to be 32 bit long.

Header (4 words):
word: number of words in code block
word: number of words in integer literal block
word: number of words in float literal block
word: number of words in string literal block

Body (variable length):
code block
integer literal block (contains a collection of 1 word long integers)
float literal block (contains a collection of 1 word long floating point numbers)
string literal block (contains a collection of strings of variable length, word-padded)
