I'm a poor programmer in that I don't own Vista or a 64-bit PC. So, whenever
I see a post with a comment like "you should use always integer for handles"
it concerns me. Currently all my apps store handles in the default type, which
is (or was?) a long. That is, I code it like this: handle=OpenProcess_(). Does
that mean I should now be doing this: handle.i=OpenProcess_()

Or, to put it another way: if I don't change my style, my apps will still run just
fine on 64-bit version of Windows, right? What's the story?

The default type with 4.30 (and therefore PB 64bit) is the integer type, so "handle=OpenProcess_()" will work just fine.

You only need to watch out in places where you added the type (structures for example).
Things like handles, #PB_Any values, PB thread, process, mutex values require the integer type.

All in all it is surprisingly easy to port a program to 64bit.
If you plan to port your stuff to 64bit some day, its not a bad idea to start using .i where you think it may be needed even now. Its less work to do in the future.

but a handle.l (long) won't work in 64 bit? Is that what your saying?

That's it. Our advice is to omit the type (unless it's really necessary), so it will stick with the integer one and will save you some headache

If you omit the type then in 64 bit its automatically assumed to be .i then, right ?

.i is the default type for both x86 and x64 as of PB 4.30.

and .i is 32bit on x86 and 64bit on x64

Well, the other way around would have been very confusing
