Well, you could use the special text commands to find out what is in the string, print it in different forms etc. You could also write it to a text file, and scan that (there was a function round here somewhere...)

Let me explain what i want to do:

I am creating a custom Level Creator for my game. As they are in a mansion and most levels are the same, it seems easy to do this. Like



at required times i would increase placex and placez.

Does this help anyone in helping me?

What?
There's no PLACE OBJECT command. POSITION OBJECT perhaps.
I think for level editors, it's best to use arrays if your game is tile-based like this. After all, a string is a type of array, but the elements are a little tricker to access. If you're using an array, the incremented variables in your for loop can be multiplied by the size of the object tile to determine the position to place the object.

If anyone wants a collection of string functions not found in DB, my string function collection is in the downloads section at http://www.matedit.com.

It has an INSTR function, (what's needed for the original post in this thread), a proper Mid$ function, a ColourText function and loads more.

I also have an instr() function, just for the sake of it...

Syntax = instr(string to be searched in, string to be looked for, nth occurence of string)

It returns the position of the string (that is the position of the first character of it) and 0 if it isn't found. The third parameter is used for different occurences. So if there was a string...

"hellomehellome"

and you said..

instr("hellomehellome", "me", 1)

It would return 6 as the 1st occurence is 6 characters along. However if you did ...

instr("hellomehellome", "me", 2)

Then it would return 13 as the second occurence of 'me' is 13 characters along.
