Remove the 'class' keyword from your function. A class method is a
different beast (with different signature) from a regular method.

This will always be invalid regardless of how nil is handled, because
you cannot add two pointers togethe
Hello Frank,
If my past post was unclear as to whether I think the constant 'nil' is an
address, then let me be clear. I quoted the Borland Object Pascal's
statement nil 'does not reference anything' I was not equating it to a zero
address value. While a pointer with a 'zero' address value shoul

From my point of view nil is like the infinite in mathematics, so it
is not range bounded and operations like nil+1 are impossible, or in
the worst case equal to nil again. Once you assigned nil to a pointer
the value becomes in range so it can be operated as usual.
Yes, doing arithmetics with N

Ok, so here is the file as it is at the moment for review so that we
can stablish a stable API (and I would like it really stable after
that).
Take into consideration that it's work in progress.
The place that I see that could be discussed is:
function GetPolyline(ANum: Cardinal): PPolyline
Hi guys
In MS Windows I use the following API functions:
1/
SetDIBits(bmap.Canvas.Handle, bmap.Handle, 0, bmap.Height, data,
PBitmapInfo(bitmapInfop)^, DIB_RGB_COLORS);
To set the pixels in a bitmap (bmap) using the colour data found in the
specified device-independent bitmap (

Frank,
I think the crux of the matter here is how to make the distinction
between a pointer with 'no value' and one that is initialized or set to
the 'lowest possible value in the range'. The quote I mentioned comes
directly from Borland's Object Pascal Langage Manual

No, you cannot catch exception t
