The bit of time I have spent in dealing with PowerBasic, with or without any Inline Assembly code, has been profitable in terms of learning new things. But since I have now taken the plunge in learning more about Inline Assembly coding as well,
I find that there are many things that have been unknown to me about the
relationship between PowerBasic and it's inline assembly capability. And there is
no doubt that some operations, if done at the assembly code level, can be done more efficiently and faster than if you try to do them at a higher instructional level.
So, this should be a good place to talk about what can and can't be done, and the how of it all.
