declaring a procedure in a procedure

[be natural*]

Is it possible to declare a procedure in a procedure?
Not calling for it, but declaring...

[Tony]

why would you want to declear a procedure inside a procedure? Thats just doesnt make any sence...

each time that procedure is called, the same one inside it is decleared over and over again.

because i have this problem...

there are 5 procedures and i will call them 1,2,3,4 and 5

inside the procedure 1, i'm calling 2 and 4
in the procedure 2, i'm calling 1 and 2
in the procedure 3, i'm calling 2
in the procedure 4, i'm calling 1 and 5
in the procedure 5, i'm calling 4

if i do this, this won't run because when i'm calling 2 in 1 then 2 has to be declared before 1 and when i also call 1 in 2 then it has to be before 2 which can't be done

how can i solve this out

I would say you need to think of a different way... a driver procedure that will have the logic to call any of the procedures based on something that may happen within one of the procedures or whatever...

might I ask exactly what you're trying to do here? like what kidn of program?

i'm making a bubble shooting game and this is the part where i'm controling the arrow that shoots the bubble.

so the first procedure draws the arrow that is pointing right up, and if i press right arrow then it will call the procedure that rotates the arrow to the right, and if i press left arrow then it will call the procedure that rotates the arrow to the left........so on and so forth

yeah, definately have a seperate driver procedure that is getting all of your keyboard input and calling the rotate procedures...

something like

code:

declare all your rotate procedures up here blah blah blah procedure main  var input : string (1)  loop   if hasch then    getch (input)    if input = rightarrow then     do the rotate to the right procedure    elsif input = leftarrow then     do the rotate to the right procedure    end if   end if  end loop end main main

i don't really get it
can u explain a bit more?
thx

forward lets you use procedures like that (all meshed together)
look it up in help for more info[/code]

[wrectify]

why can't you just use a process and fork?

[krishon]

ye, lol, that's a good question, process and fork shouldn't be too hard

[Blade]

processes i consiter bad programming, because it lags like a freak. so i would not reccomend using processes... but calling a procedure from inside another procedure will work but of course the procedure you are calling has to be written above the other... like this:

code:

procedure one lots of code in here and more code with stuff end one procedure fifty_million one end fifty_million

[Catalyst]

processes are a lazy and dirty way to program (at least in turing's case)

here how you would do procs that are intertwined

code:

forward proc One forward proc Two forward proc Three body proc One put "Hello" end One body proc Two Three end Two body proc Three One One end Three
