Mentat, you already gave a very good reason NOT to use the GOTO. You are spoiling that by adding trivial reasons, as UNTIL can be substituted - and this is what I have used for years - with a WHILE/WEND. Just let your first, convincing reason why not to use GOTOs in public stand as THE reason, sinc...

Do/loop allows you to use "until." But the operation is close.

Ralph, it isn't just my personal opinion. You don't ever, ever teach programming with goto. If you were just sharing your own code about your own project with experienced members, then I wouldn't care. Why do I care? Because newer coders write longer and longer programs as they develop. Goto makes i...

Ebbeh :shock:. Don't use GOTO. Why did they still keep that spaghetti machine from hell? Use proper loops.

Yeah. Here's I would do the whole thing if it were my project. Except that I would draw my tiles and sprite in Paint, then BLOAD them. This code runs fast enough so you can redraw every frame, without flicker. It takes care of collision detection with water and the sides of the map. screenres 640, 4...

Oh, and Qb'll fuss at you if you try to read write past it's allocated space (default is 10). You have to dim the map to the proper size.

Boundaries are simple. This is when the map comes into play: Look up the array for where you want to go, and if it's a permissive tile (path, land, etc.), then move otherwise don't. And file i/o is, well, simple for simple stuff. Like this: input "Enter file: ", fileName$ open fileName$ for input as...

Oh, so that's what the old scout is for. But if you're scrolling, you would still have to update the screen.

So what do you want to do next? Save and load tiles/sprites from files? It's not hard, pretty much like READ. Except that it doesn't fill your program like DATA.

Oh, I think it's for optimization (no point in refreshing a static screen). And for the water problem, I did a little fiddling, and the program was reading from the variable tileNumber (not the label), which didn't change because the last data statement is 3 (water). The program should read from the...

Got it to work. I had to cheat a little, since -lang QB is more FBish with it's graphics and was giving me trouble with page flipping. So I used screenLock and screenUnlock. A couple things to keep in mind: -Draw sprites after tiles, otherwise the tile will be over the sprite -Indentations help make...

Maybe MOD overflow backwards. Happened to me, and I got a cool fractal.

I think I'm going through pointer withdraw. I'll take any ptr.

Still working on the code. I don't know what I did, but it stopped putting water over everything.

Keep READ. Restore just goes back (or forward if you want).

With "RESTORE". It's used like GOTO, but with data.

Out of data means you're asking to read a data statement, but you've gone through all of them.
