hi,
i have a 2 dim. array and i want to use it in a function but get everytime a error.
when i use the 2 dim array not in a function, its work but when i use it in a function, it dont work. why???
example with 2 dim array in function:
$RegIntValArray[0] = "DA","00000406","DAN","Denmark"
test()
Function test()
$test = $RegIntValArray[0][1]
MessageBox($test,"array test",0)
EndFunction
its give me a error.
example using 2 dim array without a function
$RegIntValArray[0] = "DA","00000406","DAN","Denmark"
$test = $RegIntValArray[0][1]
MessageBox($test,"array test",0)

Got to scope your array global, this is a gotcha that gets me everytime too, like this:
Code:
Break On
Global $RegIntValArray[0]
$RegIntValArray[0] = "DA","00000406","DAN","Denmark"
$= test()
Function test()
$test = $RegIntValArray[0][1]
$= MessageBox($test,"array test",0)
EndFunction

I don't get $= test(). Or $= MessageBox. Why the $=?
And wouldn't it be better to write a function that stands totally on its own? Like one that takes an array as an argument? That way you don't need globals?
Code:
Break On
;Global $RegIntValArray[0]
$RegIntValArray[0] = "DA","00000406","DAN","Denmark"
$= test($RegIntValArray)
Function test($twoDArray)
$test = $twoDArray[0][1]
$= MessageBox($test,"array test",0)
EndFunction
I would say, as well, to use a variable for [0] and [1] pointers. Just to keep it general.

Additionally, I'm reading the kixtart manual, and it says this:
Quote:
$GlobalVariable = 10
if it's the first reference to that variable, it declares it implicitly as a GLOBAL variable, "visible everywhere and in every script during this KiXtart session." When you say:
Quote:
DIM $LocalVariable
then it's a local variable only visible in the current script. Actually this brings up a question: theoretically, it's bad style to do this:
Code:
for each $group in $groups
?$group
$Message = $Message + " blah" + @crlf
next
$Message = $Message + " more blah" + @crlf
isn't it? In my opinion, it shouldn't even recognize $Message outside of the for loop. But it does recognize it because $Message is declared implicitly as a Global. This encourages bad style.
Keep on kiXin it solo style!
