Convert Dword - fielden - 03-06-2005
How would you convert this PowerBasic code to freebasic
Local Size as Dword
Size = MAKDWD(x, y)
Thanks for any help

With macros in 0.12, you can do like:
#define MAKDWD(x,y) (cint(x) shl 16 or cint(y))
dim size as uinteger ' or unsigned integer
size = MAKDWD( x, y )

Can we do variable arguements and multi-line macros too?
Also, how is pointer math coming? ie: *(foo+bar) = something

Code:
[added] "*([@]variable +|- expression)" and "*@variable" support (v1c)
[added] pointer indexing support, as in "myptr[idx]" (v1c)Convert Dword - 1000101 - 03-06-2005
That doesn't help when adding two (or more) unrelated pointers together.

That makes no sense. Say you have ptr1 = 100 and ptr2 = 200, both added = 300, that points to?? Neverland? :P
Try that in GCC and it will die with the "invalid operands to binary +" error.[/quote]
