arc.lang, an esolang using my username!

The only valid instruction is arc
buuuuuut...
✨ captialization ✨

Theory:

There are two things in arc, the stack, and the operating var, the op var is a place in stack. You can move around the opperating var

Instructions:

code	instruction
arc	increment op
aRc	decrement op
Arc	move op up in stack
arC	move op down in stack
ARc	increment op by stack down
aRC	decrement op by stack down
ArC	print out stack at op as ascii
ARC	print out stack at op
