Why does adding a semicolon to this program,



like this,



create different results?

mi keety tot mi gramer?

By using a semicolon at the end of a printable text, you are telling DB that you want the next print to take place right after it. It effectively sets the cursor there, so that when you simply use print by itself again the text prints there.

Without having the semicolon there, DB moves the cursor down to the next line so that the next printing take place there.

I prefer to use the 'text' statement myself instead of using 'print'.

So it's like a really short command? What else does it do?

mi keety tot mi gramer?

You can string together different things with it:

So what it really does is tell DarkBASIC that the next command should take place right after the first one? Including putting the cursor right after the previous text? Or does all it do just change the position of the cursor? Does it work with other commands?

It only sets the position of the cursor to right after whatever is printed. It only works with 'print' and will not work with the 'text' command. I do not know any other command that directly works with this. What is it that you are trying to do?

I'm just curious. I'm one of those "Have to Know How and Why" people when it comes to programming.

Oh, by the way, when you have the


Two things:

First of all, using

won't get any input.

Using something like

will check that immediate input to see if it was a space (btw, haven't tested, hope it works)

Second, using

Will leave a piece of your memory (small, but it still is) gone.
This is because gosub expects to see a
to have it come back, where goto just goes to the label

Use something more like



or


To save memory and some brainrackingness.

Good luck!

Actually, it does. It is unusual how the iron programmer did it, but the code actually does work. Pressing the SPACEBAR does indeed exit the program.

Quote: "Using something like
if inkey$() = " ""

That does work, but why not just use the built in 'spacekey()' command?

Quote: "Use something more like
goto quit

quit:
end"

There is great division among coders as to whether or not to use goto. I do not want to get into an in-depth debate about it, but you could easily code this so that a goto is unneeded. Like this:

About the "1 = spacekey()" part, that's how it says to use it in the syntax. I used to use "spacekey() = 1" but for no apparent reason I switched to the way I currently use.

Is exit another command for end or something?

Exit lets you escape loops such as For..Next Do..Loop and such. You may just want to type in the commands you dont know then click under it and press F1 for help. It's faster than asking someone on the boards.

Sadly I know that ditto is a pokemon that replicates other pokemon, it is one of the few ones that has a logical name because that's exactly what the word ditto means, a replica of something, in this case a replica of a previous remark.

Well that's my trivia for the day
