Post subject:  info in procedures
I am sorry for making so many topics....but...

anyways..i was wondering how you could trasfer info from inside one procedure to antoher

For exmple.
I figured out a score in procedure A. However, when i try to use the same variable for the score in procedure B, it does not reconize it and says it is not delcared."

My question is...what could i use to transfer my score from one proc to antoher?

Declare the variable outside the procedure.

Turing:
var foo : string

procedure hello
   foo := "Hello"
end hello

procedure world
   foo := "world"
end world


But, this is just silly. Instead, you should use functions, which can calculate some new value, and return it to the program. You can then do whatever you want with that value.

Turing:
function hello : string
   result "Hello"
end hello

function world : string
   result "world"
end world

Essentially yes.

code:
function foo : int
   result 42
end foo


Of course, yours would likely be more sophisticated.
