This operation is used to get the value of a symbol. It takes a symbol from the top of the stack and pushes the value associated with that symbol. The symbol is searched in the current directory and if it is not found, it will check the parent directory. This continues until it is found or it reaches the HOME directory and it is unable to find it. If unable to find the symbol when traversing the directories, an error is returned.
