Difficulty: Hard
CHALLENGE: Programm a programm, which parses a command-String and outputs the result.
EXAMPLE:
write ("Hello, World")
RESULT:
Hello, World
VOILA: you have the first step to building an interpreter.
EXTENSION: Write a routine, which removes blank spaces outside of texts (inside quotes), so the interpreter doesn't take notice of them
EXTENSION2: Make the parser so, that Concatenating strings with a plus is allowed!
EXAMPLE (extension 2):
write ("Hello, " + "world")
RESULT (ex2):
Hello, world
