Simple programs

Cat program

A repeating cat program, terminating only as a sequela of a space character's (Bleph! character code: 0) specification, is presented:

^#[:~#:]

Hello world!

This program issues the message “Hello world!” to the standard output:

A very boring guessing game

Generates in an aleatory fashion either the number zero (0) or one (1) on the stack, queries the standard input for a character representing a choice from the same membership, and prints, upon a successful equiparation, the value zero (0); otherwise, if the user input deviates from the random number, signifies the mismatch via a -1 output:

^+
^?
^#----------------------------------------------------------------------
@:O

Addition

^#^#!O

Subtraction

^#^#@O
