some of you may find it of some use.... some not.

Some folk may find some of those functions useful. However, I noticed that you often check to see if memblock 100 (or 200(or 300(or 400))) exists and if it does then you delete it because your function needs it!
May I suggest that you search for a free memblock instead of deleting a memblock that the user (or in this case - coder) may find vitally useful and really doesn't want to be deleted.

+ Code Snippet

Function FreeMemBlock()
	
	Mb = 1
	repeat
		if Memblock Exist(Mb) = 0
			Found = 1
		else
			inc Mb
		endif
	until Found
	
EndFunction Mb

Also, your function to copy a bitmap already exists as a DBP command. Check out the Copy Bitmap command (it also allows images to be scaled it the bitmaps are of unequal sizes).

@ Scraggle,

Thanks for the feedback. You're quite right. Made the memblock numbers very high so as to avoid program memblocks. However, could do a search routine (within a certain bracket) for free memblocks. Actually, now I seem to think about it IanM had a free dll to do just that...

I suppose the notional programmer could adjust the memblock numbers as well to suit.

With the CopyBmp command I was just getting carried away.

Before I got going on this I was really just after a few commands to allow me to draw or get colour at pixel within images...

Just a thought - if I alter an image using the above functions, what happens to that same image as utilised in a sprite - (is the image data in the sprite now independent)? if yes, thought so, if no, couldnt I write a function for sprite collision?

A fast way of finding a free memblock..

+ Code Snippet

MemB As Integer

Repeat
  MemB = rnd(1000) + 1000
Until not memblock exist(MemB)

Thanks for this set of functions anyway - takes me a lot of work.

Or a method that doesn't rely on random numbers

+ Code Snippet

Function FreeMemblock()
   Repeat
      Inc Ret
   Until Memblock Exist(Ret) = 0
EndFunction Ret

Hallowed are the ori.
