Alpha

Alpha is an esoteric programming language that is part of a series by User:Infinitehexagon on Greek esolangs that will be a derivative of the previous esolang with more commands, less commands, or modified commands. So far it has 6 commands.

Commands

Alpha	Description
+	Increment the accumulator by the amount of α(Alpha) following it
-	reverse the value of the accumulator eg. 72->27. If the reversed value is greater than 255 then set the accumulator to 0.
$	output the accumulator's Unicode value
[	jump to the "]" instruction by the amount of times α(Alpha) follows it. (Leave blank for infinite loop)
]	Jump back to the "[" instruction.
a."(instructions)"	read input of instructions and execute them in the program, then append the result into the accumulator

Input Problem

The "a" command does not count as input, as it doesn't necessarily take user input, but takes input as a self-interpreter.
