Orca is an esoteric programming language designed to quickly create procedural sequencers, in which every letter of the alphabet is an operation, where lowercase letters operate on bang, uppercase letters operate each frame.
This is a minimalist implementation of the basic operators created for educational purposes. To try a complete environment with client and server, see Orca.
You must have SDL2 and portmidi.

.
A
add(a b): Outputs sum of inputs.B
subtract(a b): Outputs difference of inputs.C
clock(rate mod): Outputs modulo of frame.D
delay(rate mod): Bangs on modulo of frame.E
east: Moves eastward, or bangs.F
if(a b): Bangs if inputs are equal.G
generator(x y len): Writes operands with offset.H
halt: Halts southward operand.I
increment(step mod): Increments southward operand.J
jumper(val): Outputs northward operand.K
konkat(len): Reads multiple variables.L
less(a b): Outputs smallest of inputs.M
multiply(a b): Outputs product of inputs.N
north: Moves Northward, or bangs.O
read(x y read): Reads operand with offset.P
push(len key val): Writes eastward operand.Q
query(x y len): Reads operands with offset.R
random(min max): Outputs random value.S
south: Moves southward, or bangs.T
track(key len val): Reads eastward operand.U
