Returning to a Procedure

[Guest]

Is it possible to say, have this:

code:

proc MAP_1 if (x = true) then MAP_2 end MAP_1 proc MAP_2 if (x = false) then MAP_1 end MAP_2

I really need this to help me in my RPG to make it so when I touch the town I enter it, then when I touch the gate to the outside, I come back out.

This is the circular dependance problem. No, in a language like turing, It is not possible to have that directly. HOWEVER, there are ways to simulate things like this. Read Cervantes' topic in the tutorials about turing as a functional language. You can simulate a procedure using a function. There are a couple other options, depending on what you need done.

#1) You could use recursion,

code:

procedure MAP_1 (x : int)    if x > 0 then       MAP_1 (x - 1)    end if end MAP_1

#2) You could have a variable that returns from the procedure, and tells you if you need to call the second procedure or not.

#3) Use a different programming language (One that is compiled not interpreted [I believe I said that right... someone correct me if not])

well you need an exit condition on one of the proc.. so that it doesnt get stuck in a circle...

lol, mystic vegeta, its not possible. It'll give you the error "MAP_2" has not been declared. Turing works linearly. Ready my previous post, and try it out if you don't believe me

I thought you were familiar with forward and body procs...

code:

var x : boolean forward proc MAP_2 proc MAP_1     if (x = true) then         MAP_2     end if end MAP_1 body proc MAP_2     if (x = false) then         MAP_1     end if end MAP_2

lol, nope. I've used em in classes, but only to have multiple copies of the same procedure . (Neither was vahnx. You gotta explain that when helping )

Thanks so much MysticVegeta! I've been wondering this since i started Turing like 4/5ths a semester ago. You truly are a programming god. Did I ever tell you that.... I...... Love you.... (*kiss*)

Also, is there a way to also transfer a variable from inside that body procedure?

[TheOneTrueGod]

either global variables or

forward proc MAP_2 (var x : int, y : boolean /*etc*/)

Do you mean transfer a variable from inside to the outside or from outside to the inside..

Cause if its from outside to inside then truegod's post will help you else if its from inside to outside then you need "functions" that return a value like..

code:

fcn square (x : int) : int       return x**2 end square put square (2) % Outputs 4 var squaredNumber := square (someNumber) % Transfers the value from inside the function to the outside by storing the returning value in "squaredNumber" variable.

Yeah for my game I just made it a global variable, so it doesnt really matter now. And I could use () probably.
