Alumin is a language whose commands are entirely lowercase letters, and nothing else. It operates on a stack.
a push the sum of the top two members on stack b push modulo of top two members on stack c push difference between top two members on stack d duplicate top of stack e push equality of top two members f read commands until the next f; folds the stack over those commands. g divide top two members on stack h a run of N hs in a row pushes the number N i read a character from stdin j read a number from stdin k discard top of stack l push the length of the stack m same as f, but maps instead of folds. n print a number o print top of stack as a character p end loop (while positive) q start loop (while positive) r reverse stack s pop a stack off the stack stack t push product of top two members of stack u push greater of top two members of stack v push lesser of top two members of stack w pop top N members into a new stack; put old stack onto the stack stack x push a random number between 0 and the top of the stack (right exclusive) if the top of the stack is 0, push a random float between 0 and 1 y swap top two members on stack z push 0
