Alphabet Stew

Brainfuck derivative using only letters (a – z) Created by User:DMC

Concept

 * A stack based esoteric programming language with exactly 26 commands
 * Each command is represented by a single character [a - z]
 * Numbers [0 - 9] are not used
 * Any character not within the set [a-z] is ignored
 * spaces and line feeds may be used for clarity

Description

 * an infinite array of cells
 * pc - program counter
 * p - data pointer
 * top - stack pointer
 * all memory is initialized to zero
 * commands that require two values to be pushed will pop two values and push the result onto the stack
 * '!' diagnostic command to print out memoiy cells up to highest value of the data pointer, does not have to be implemented
