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 ' '.
