Nondescript is a programming language by User:PixelatedStarfish. It is a genericized, stack-based, language designed such that it has a simple interpreter. It supports various stack operations with minimal syntax. Riveting, isn't it? It was created for the language Bedtime as a base language. Bedtime compiles to Nondescript.

Commands

Commands are simple integers separated by newlines. Arguments for a command are separated by a space.

-1 - Comment. The '#' can also be a comment.
 0 - Print top of stack
 1 - Print ASCII value
 2 - Print top of stack as ASCII
 3 - Pop
 4 - Push [0 if no argument]
 5 - ADD V to value at top of stack [or 1]
 6 - Label L
 7 - GOTO L (Label) [or start]
 8 - GOTO L if 0 [or start]
 9 - Input. Singer char is default. Use argument 1 for an integer and 2 for a string.
10 - Duplicate top and push [or push 0 if empty]
11 - Shuffle Stack [unless empty]
12 - Halt
13 - No operation

Note that stack values range from 0 to 255. Adding 1 to 255 sets a value to zero.
