Help with flexible arrays and procedures

[battfel]

What is it you are trying to achieve?
I am wondering If there is any way to use flexible arrays as a parameter in a procedure, so that I can modify the array within the procedure.


What is the problem you are having?
So far, it doesn't seem like this is possible. It might just be that Turing doesn't support it.


Describe what you have tried to solve this problem
I tried declaring the procedure like :

Turing:

procedure bulletmovements (var a : flexible array 1..* of bulletdata)

And I tried declaring the procedure with a normal array as a parameter, which does work, but then functions like 'upper()' won't work within it. I looked around the forums a bit and couldn't find much about this problem. My code has two long for loop sections that are practically the same other than different flexible array variables throughout, so it would have been nice to just condense it. As you'll see by the way, they are flexible arrays of a custom type, which I don't know if that matters, it probably shouldn't.

Turing:

for i : 1 .. upper (bluebullet)         if bluebullet (i).x - bluebullet (i).xvel > maxx - 3 then             bluebullet (i).xvel *= -1             bluebullet (i).yvel *= -1         elsif bluebullet (i).x - bluebullet (i).xvel < 3 then             bluebullet (i).xvel *= -1             bluebullet (i).yvel *= -1         end if         if bluebullet (i).y + bluebullet (i).yvel > maxy - 3 then             bluebullet (i).xvel *= -1             bluebullet (i).yvel *= -1         elsif bluebullet (i).y + bluebullet (i).yvel < 3 then             bluebullet (i).xvel *= -1             bluebullet (i).yvel *= -1         end if         if bluebullet (i).timealive > 333 then             for j : i .. upper (bluebullet) - 1                 bluebullet (j).x := bluebullet (j + 1).x                 bluebullet (j).y := bluebullet (j + 1).y                 bluebullet (j).xvel := bluebullet (j + 1).xvel                 bluebullet (j).yvel := bluebullet (j + 1).yvel                 bluebullet (j).timealive := bluebullet (j + 1).timealive             end for             new bluebullet, upper (bluebullet) - 1             exit         else             bluebullet (i).x -= bluebullet (i).xvel             bluebullet (i).y += bluebullet (i).yvel             bluebullet (i).timealive += 1         end if         if Math.Distance (bluebullet(i).x, bluebullet(i).y, rx + 35, ry + 35) < 15 then             reddeath := true             gameover := true             for j : i .. upper (bluebullet) - 1                 bluebullet (j).x := bluebullet (j + 1).x                 bluebullet (j).y := bluebullet (j + 1).y                 bluebullet (j).xvel := bluebullet (j + 1).xvel                 bluebullet (j).yvel := bluebullet (j + 1).yvel                 bluebullet (j).timealive := bluebullet (j + 1).timealive             end for             new bluebullet, upper (bluebullet) - 1             exit         end if     end for     for i : 1 .. upper (redbullet)         if redbullet (i).x - redbullet (i).xvel > maxx - 3 then             redbullet (i).xvel *= -1             redbullet (i).yvel *= -1         elsif redbullet (i).x - redbullet (i).xvel < 3 then             redbullet (i).xvel *= -1             redbullet (i).yvel *= -1         end if         if redbullet (i).y + redbullet (i).yvel > maxy - 3 then             redbullet (i).xvel *= -1             redbullet (i).yvel *= -1         elsif redbullet (i).y + redbullet (i).yvel < 3 then             redbullet (i).xvel *= -1             redbullet (i).yvel *= -1         end if         if redbullet (i).timealive > 333 then             for j : i .. upper (redbullet) - 1                 redbullet (j).x := redbullet (j + 1).x                 redbullet (j).y := redbullet (j + 1).y                 redbullet (j).xvel := redbullet (j + 1).xvel                 redbullet (j).yvel := redbullet (j + 1).yvel                 redbullet (j).timealive := redbullet (j + 1).timealive             end for             new redbullet, upper (redbullet) - 1             exit         else             redbullet (i).x -= redbullet (i).xvel             redbullet (i).y += redbullet (i).yvel             redbullet (i).timealive += 1         end if         if Math.Distance (redbullet(i).x, redbullet(i).y, x + 35, y + 35) < 15 then             bluedeath := true             gameover := true             for j : i .. upper (redbullet) - 1                 redbullet (j).x := redbullet (j + 1).x                 redbullet (j).y := redbullet (j + 1).y                 redbullet (j).xvel := redbullet (j + 1).xvel                 redbullet (j).yvel := redbullet (j + 1).yvel                 redbullet (j).timealive := redbullet (j + 1).timealive             end for             new redbullet, upper (redbullet) - 1             exit         end if     end for

Maybe there is a workaround or something. It's not a huge deal either to just leave the code as is, I'm more curious as to if it is possible to do this

According to the documentation:

"There is no flexible array parameter type, although a flexible array can be passed to an array parameter with “*” as the upper bound."
