Hey, I just wanted to start this because I just had a crazy thought

Before anyone puts a comment without understanding what it is that I am saying, [ I am not trying to do any of this I am just wondering is it possible?, not "THAT WOULD BE IMPOSSIBLE BECAUSE YOU WOULD HAVE TO blah blah blah"]

I want to know what are some of the things you could do with DBPro by bending it the way it was not ment to be used..

Like could you create your own language, or compiler with DBPro

The reason I ask this is because personally I think you could
depending on these factors
1. Know machine langauge and all that good junk
2. Could wait on it to compile something it would probably be really really slow but I think its possible
3. Have no life and alot of time / knowledge on your hand..

I would like input because I find it interesting and its just one of those thoughts I want to know if it isnt possible, why it wouldnt be, not just a pointless comment like "That is not possible" It would just leave me to wonder what it lacks from doing it? Maybe not being able to write specific data or something

I believe, in my opinion, it IS possible. But, but, but. It would take you to think extrovertly and outside the box.

Linked lists are an important feature for a compiler etc so you would need to make an equivalent,


I think it could be done.

Yeah, it can be done because you can manipulate memory at a byte-level.

You could make your own language using Barnskis free LUA, i believe, to call DBP commands from scripts. But it's against the terms of the license so i would guess you'd get sued, unless TCG sold it, so don't do it

You can make a very archaic virus scanner for the now defunc .com files, using a memblock to map an executable and scan for "signature strings" of commands that are associated with a virus.
For example, lets suppose the virus has the following instructions:
E8 00 00 (CALL 0103H) 5D (POP BP) 81 ED 03 01 (SUB BP, 103H)
These are typical instructions found on an old com file infector.
You would need to map the file onto a memeblock, then check byte by byte and see if this pattern is the same as the scan string.

I always wanted someone to make a Winamp type Visualizer from DB/DBPro. Something that analyses a peice of music, and responds to the sounds.

I'm pretty certain you could write your own compiler, but it wouldn't be very fast, and the limitations of DBP could make certain things tricky.

Any language that has the ability to process strings can be used to write a compiler. If your not really bothered about compilation speed (which isn't that much of a big deal) then there is no problem. However I wouldn't suggest writing an interpreter in DBP because I can't imagine it being very fast.

I think there are a couple, Van B springs to mind.

You can use the advanced array commands to treat arrays as linked lists (which is probably what they are anyway). array insert at bottom and array count() are two commands that I use, alot.

Preprocessor, yes. Compiler, no.

Of course it's possible. Kyruss is rewritten in DB classic. You can write a compiler in virtually anything!

How about memblocks with a few bytes reserved to "point" to the next memblock number?

Yes that may work but equally so could an array implementation I suppose. I'll have to try it when I have more time

I am making a compiler in vb.net, and it is awesomely easy to do. (Except for writing the assembler code to output, lol) All you need is to loop through a string one word at a time, and you can write a compiler. The dictionary class in VB.net is also very useful, and surprisingly easy to port to DBP.

Diggsey, cool sounds good.

I'm currently writing an Assembler in C++.NET (but coding in Native C++)


It's coming along quite well, currently working on parsing.

Preprocessor, yes. Compiler, no."

A compiler could be done with a few string splitting commands, arrays and some File IO. It would get messy fast but is absolutly 100% possible.
Lots of people are writing some kind of parser it seems. I was writing one which took a subset of basic and converted it into MIL bytecode but I'm real lazy and haven't done much on it for the last week or so. I've been messing around writing parsers and such for the last 4 years but I'm not great at finishing things, I've learnt a truck load though!

That's cool, because my compiler compiles to assembler, so it would be awesome if we could link them together somehow Especially cool, because if you know assembler you might be able to help me out with my compiler It can parse almost everything that will be in the finished language, and produces pseudo assembler code, but no real code yet

What I mean, is that there is a lot more to compilation than just processing the text input

Yes of course there is, I was pointing out what language features are required.
