Datatypes:
pointer = <>
byte = []
data = ()
location (16 bit) = {}

Instructions:
Arithmetic:
SET - set <target> [byte]
CLR - clear <target>
CPY - copy <source> <target>
ADD - add <source1> <source2> <target>
SUB - subtract <source1> <source2> <target>
MLT - multiply <source1> <source2> <target>
INC - increment <source/target>
DEC - decrement <source/target>
BSL - shift left <source> <target>
BSR - shift right <source> <target>

Misc:
EXT - exit
RND - random number <min> <max> <target>
SIN - sin of <source> <target> (0-255)
COS - cos of <source> <target> (0-255)

Control Flow:
JMP - jump TO:"location name"
LOC - jump point LOC:"location name"
EQL - equals <source1> <source2> TO:"location name"
NEQ - not equals <source1> <source2> TO:"location name"
LTH - less than <source1> <source2> TO:"location name"
GTH - greater than <source1> <source2> TO:"location name"
PSH - save cursor position
POP - load cursor position
