Help with Arrays

[sandyd]

Hi all,

Having a bit of a problem getting my head round array. See the following code:

#include <file.au3>
#include <Array.au3> 

Dim $WordList, $As[1]

_FileReadToArray('a.txt',$WordList)

For $i = 1 To $WordList[0]
 If StringLower(StringLeft($WordList[$i],3)) = 'add' Then _ArrayAdd($As,$WordList[$i])
Next
 
_ArrayDisplay($As,'ADD ...')

MsgBox(0,'',$As[0])

A file with lots of words begining with the letter A is read. I then try to filter them down by searching for the first 3 letters to be add.

When I try to display the results, it cant determine the number of items in the array. I have checked by outputting $As[0] which shows blank.

Any ideas?

If the msgbox is not there, then you probably have too much information to display... Use Ubound($As) - 1 instead of $As[0] and see what you get

Cheers for the replies,

I think I'll stick with UBound, more generic and less for me to worry about.
