Uuhh... has something like this been done already? If it has... sorry... you'll probably want
to use the other one ;). This contains functions to work with INI files. Any bugs or anything,
e-mail me... the address is at the end of this if/endif block. Here are the functions:
***********************************************************************************************
 OpenINI(INIFile$) as Integer 
     Opens the INI file... call this first, always
 	returns 0 if it's ok, -1 if it's not.
 
 ReadKey$(Section$, Key$)
     Gets the value of Key$ in Section$
 	returns the value of Key$ (if found)
 	returns "Section not found" if Section$ isn't found
 	returns "Key not found" if Key$ isn't found
 
 WriteKey(Section$, Key$, Value$) as Integer
     Writes Value$ to Key$ in Section$
 	returns 0 if it's ok, -1 if Section$ wasn't found
 	
 WriteSection(Section$) (this is a sub) <-- writes a section.
 
 DeleteKey(Section$, Key$) as Integer <-- Figure this one out ;-)
 	returns 0 if it's ok
 	returns -1 if Section$ wasn't found
 	returns -2 if Key$ wasn't found
 	
 DeleteSection(Section$) as Integer <-- hmm... wonder what this does....
 	returns 0 if it's ok
 	returns -1 if Section$ wasn't found
 	
 SaveINI(INIFile$) as Integer <-- hmmmm......
 	returns 0 if it's ok, -1 if it's not
***********************************************************************************************
 
Hopefully, this can help you out... a little :). I should add code to ignore a line (e.g. not
put the line into INIArray() if it's blank, but I want the INI file to be written exactly as
it was read... so I didn't. Erm... sorry for the messy code, I just sorta stick things in as
they come into my head. Oh, btw, I don't like ARRAY SCAN. I really don't. Oh, second btw... I
think this thing is pretty slow. Please, please, modify it... make it faster... It'd be cool to
get this thing going fast... Oh, third btw... I think there are API calls to write/read from
INI files, but from what I saw they only wrote/read to win.ini or the registry... Then again,
I could be wrong. I only looked at it for a couple of minutes.

Oh yea, final warning: Don't use INIArray(), INISectionIndex(), or INISectionIndexMax in your
program. If you do, you could mess this up. Blah...

function OpenINI(INIFile$) as integer
$if 0
OK, here's how this little baby works...
1) Check to see if the file exists (if not, return -1)
2) Open the file
3) Put each line of the file into INIArray()
4) If the line begins with [ and ends with ] then it's a section, and we should put the number
   into INISectionIndex()... hence the name 'index' hehehe
5) End the function.

function ReadKey$(Section$, Key$)
$if 0
Here is how this one works:
1) Add [ or ] to Section$ if necessary
2) Use INISectionIndex() to match the section... if section isn't found, say so.
3) Scan INIArray() from the section to the next section (or the end of the array) for Key$
4) If Key$ isn't found, say so and exit
5) Get the value of Key$ and send it down... then exit.
