Fear

Fear is an esoteric programming language that gives you esolangaphobia. It has six instructions: i, o, +, -, j and r.

Instructions

It has one variable. i takes input from the user and sets the variable to the first character of what they have written. If they haven't written anything then the variable is set to ' ' (a space). o prints the variable. + shifts the variable forwards to the next ASCII value. For example 'a' becomes 'b' and 'z' becomes '{'. - does the opposite. j jumps to the beginning of the program. r resets the variable to ' '.
