Problem Bug with File UDF _FileReadToArray()?

Recommended Posts


When I try to do something like the following the Redim truncates my array. It works fine every other time I use it. It also work if I using FileReadLine() in a loop to populate my array. I was wondering if this was a know issue with the File UDF?

#include <File.au3>
#include <Array.au3>
Local $filearr[1]



ReDim $filearr[ubound($filearr)][2]

It does not "truncate" it - it deletes the content totally! :) And it is not a "bug".

If you want to retain the existing data in an array, there is no way to increase the number of dimensions - you have to copy the data from the existing array to another array with the required number of dimensions. Using any form of declaration (Global/Local/Dim/Redim) and changing the number of dimensions will erase all existing elements from the array.

However, by using ReDim you can alter the size of existing dimensions without deleting existing elements.

Do not get confused between the number of dimensions (the number of [ ] after the array name) and the size of existing dimensions (changing the number within an existing [ ]).

All clear? ;)
