Basic array question

[saywell]

I've looked in wiki and searched the fora and helpfiles, but this may be too basic a question!

If I want to clear a string I can use

$sString = ""

.

Is there a similar simple way to clear the contents of an array? Redim is the nearest I've seen, but this isn't a quick and dirty way like the string example. Or would I have to specify that each element of the array = "" using a loop?

See the help file for "Dim / Global / Local / Const":

"To erase an array (maybe because it is a large global array and you want to free the memory), simply assign a single value to it:

$array = 0

This will free the array and convert it back to the single value of 0."

Thanks - I thought there'd be a simple way, just couldn't find it!!

I knew that! ;-) Its set out in the Help File.

However - I have built a 2dimensional array, and now I want to extract item x from the second dimension and I can not even find an example... Could someone perhaps point me to more 'extensive' array examples? I have too little knowlegde to figure out how to do this and the Help File is all about Dim/ReDim and _Array... functions, but not how to use specific items from a multidimensional array. It probably simple, but I do not know.

Please?

Skysnake,

Have you read the Arrays tutorial in the Wiki? It covers 2D arrays as well.

In general, to extract an element from the array, you need to specify the index/indices:

; Declare a 1D array
Global $aArray_1D[2] = ["A", "B"]

; Read the contents
ConsoleWrite($aArray_1D[0] & " - " & $aArray_1D[1] & @CRLF)

ConsoleWrite(@CRLF)

; Declare a 2D array
Global $aArray_2D[2][2] = [["A", "B"], ["X", "Y"]]

; Read the contents
ConsoleWrite($aArray_2D[0][0] & " - " & $aArray_2D[0][1] & @CRLF & $aArray_2D[1][0] & " - " & $aArray_2D[1][1] & @CRLF)

If you posted a bit of code we might be able to help a bit more precisely.

Thanks, great help. Why can I not download the wiki as single file for off-line usage? Or am I just being backward?

to pass a specific value from the second dimension I could use, right

$getvalue = $myArray[3][2]

this would put the third array item from the second dimension into my $getvalue, right? problem is all examples seem to assume that people KNOW how to do this, and I don't :-(

are there samples about with predefined arrays like days of the week etc that one can just pick up and use or must I build my own?

eg

[day1, sunday]

[day2, monday]

or

[1, one, first]

[2, two, second]

etc?

Thanks for bothering with me.
