Return without a previous gosub act as END, please make error message "RETURN without GOSUB"
Two labels with same name do not cause a error, please make errror message "Double label definition". Only the second label is executed, this makes me mad if I forget to remove dummy labels before.
FOR without NEXT causes error "can not close nest at line (last line of program)", this is because NEXT ignores any variable name (NEXT a is the same as only NEXT). Do not ignore variable names, so the compilen will be able to say which nest (line, with FOR command highlighted, and name of variable displayed) was not closed.

Try copying from bitmap 0 to another, so that you can refresh only part of the screen.

COmpiler will crash every time.

On my machines 7,7,23 is printed, instead of 7,1,23 - which did you get ?
The problem is that passing the global value like that seems to corrupt the next variable (which is rather naughty).

Whats the size of your core.dll (I'm assuming that is where the problem is) ? And are you using Patch 4?

In your programs, you've got rid of the global command - which is an important part of the error...

Hmmm, Lee still not fixed the nice crash at copying bitmap 0 to another one? Thank god we rewrote the code (in Patch 1 era) to not trying to copy from Bitmap 0. But GET IMAGE and PASTE it in another bitmap is slower. I wonder it this bug will be fixed in Patch 255.

why not simply create 2 bitmaps and then use a memblock to pass the data across ... as long as the resource for the second bitmap is there (no matter the space/size allocated) you can then copy the memblock directly do it as a memory copy rather than a function


ptr as DWORD
*ptr=7
test(1,23)
wait key

function test(d as DWORD,dx as DWORD)
text 0,0,str$(*ptr)+" "+str$(d)+" "+str$(dx)
endfunction


that should also return the same value (^_^) - not global involved

Raven - you've assigned 7 to *ptr without defining a memory location - that could cause a nasty crash...

@Raven: It is a workaround that works, but this does not change the fact that COPY BITMAP has a bug We have found out some workarounds ourself, so we draw on Bitmap 1, then copy the content to any other Bitmap we want. But why Lee still did not fix this bug, that is known since the beginning of DB Pro existence, this is the question.

"it's bloody late i ain't wrapping my brain around that... and anytime i can push more people to use the advanced features of pro - i will (yw)"

Raven, DBPro is meant to make games progamming easy, lengthy workarounds like the one you suggested shouldn't be necessary. I want to use memblocks on my terms, not when DBS produce buggy DLLs.
