& push integer
~ push ascii
( push tanstore (same effect on string mode)
" string mode
$ pop and delete
: duplicate top
@ ends program
0-9 pushes integer
* integer multi (like *87 would push 87)
s starting place, starts off going right
i increment top
d decrement top
q square top (no 256 behaviour like in Deadfish)
r pushes the value in position n (where n is the top)
; repeats previous command until stack is empty, then continues
[ goes to previous stack
] goes to next stack

Uppercase letters are warps like in Asciidots. Like this:

s   A
 A     v
       *
       1
       2

Would push 12.

*? pushes a random number between 0 and the top of stack. If nothing is in stack, then ten is used.
