Instruction	Desc
a.b.+	Var a += var b
a.b.-	Var a -= var b
a.b.*	Var a *= var b
a.b./	Var a /= var b
a.b.%	Var a %= var b
a.b.v	Sets value of var a by value b, but if b is $ symbol, value takes from input
a.b.>	Var a = var b
a.#	Output var a
a.@	Output var a as ascii
.!	Clears output
.~	Stops program
a.^	Jumps to label a
a.b.c.!0	If value of var a == 0, jumps to label b, else jumps to label c
a.b.c.!1	If value of var a == 1, jumps to label b, else jumps to label c
a.b.c.d.!=	If value of var a == value of var b, jumps to label c, else jumps to label d
a.b.c.d.!==	If value of var a != value of var b, jumps to label c, else jumps to label d
