Can you do cross referencing in Turing?

[HazySmoke)345]

The following code does not work as expected...

code:

procedure f1(d: int)     put d     if d > 0 then         f2(d-1)     end if end f1 procedure f2(d: int)     put d     if d > 0 then         f1(d-1)     end if end f2 f1(6)

... because Turing can't call f2 while in f1. Is that possible to fix?

Yes it is. Look up the forward keyword in Turing help.

You must be careful when doing this, though, since it's easy to create an endless loop of procedure calls. For example f1 calls f2, f2 calls f1, f1 calls f2, and so on until the program crashes or just stops running.

I noticed your procs are the same. If this is intentional, then what you are intending is called recursion!

code:

procedure f1(d: int)     put d     if d > 0 then         f1(d-1)     end if end f1

No need for two procs!

Thanks for the hint. I only have about 3 bits to give away, though...

Actually, I wrote the source code that way to simplify the problem I really had, the two procedures in my real program are in fact very different. Thanks for helping anyways.
