Hi,

coming from PowerBASIC and meeting PureBasic now, I'm wondering we can't set arrays as parameters to procedures. Maybe this will be possible in 3.x, Fred?

Until this, can I set for example a pointer to the first element of an array and accessing its data inside a procedure. Has PureBasic an array-descriptor (espacially intersting for string arrays)? How are Arrays managed from PureBasic?

Thanks for any help and informations!

Structure wptr

EndStructure

If OpenConsole()
  Dim foo.w(5)
  *ptr.wptr = @foo(0)
  For i = 0 To 4
    foo(i) = i * 3
    PrintN(Str(*ptr\w[i]))
  Next
  Print("Press >RETURN< to end...")
  Input()
EndIf

Sorry Tinman, wrong Manipulation..

Hi tinman,

thanks for your tip!

...but your code ends in V3.0 with a windows GPF while accessing *ptr\w.

What does that mean? And why did you edit my message?

This works fine (I should not have been so lazy with the first example), and I use this trick in a lot of other places without any problems (it has been tested on Win95, Win98 and WinXP).

Code: Select all

Structure wptr
  w.w[0]
EndStructure

Dim foo.w(5)
*ptr.wptr = @foo(0)
If OpenConsole()
    For i=0 To 4
        foo(i)=i*3
        PrintN(Str(*ptr\w[i]))
    Next
    Input()
    CloseConsole()
EndIf
End

It's not minimalist - I'm increasing efficiency by reducing input effort.

Fred was here...

Fred,

thanks, sorry, until now I didn't use the console and looked not in the right way to the debugger window - oh, oh, programmers....

Thanks to both for your help!

I've edited your message to copy/paste the code correctty and test it.. And I replied directly in your window by mistake. So I've overriden your text (and no way to go back).

Ah, OK. No problem. I've posted a (hopefully) working version now anyway
