_FileListToArray() does not returnarray if no file s found

[RickJ]

if _FileListToArray() doesn't find any files it does not return an array. It should probably return an array of one or two elements with the first element having a value of zero.

Currently @error is set to a value of 4 to indicate no files found so it's possible to workaround this. IMHO a function should always return the same data type.

Assuming you are writing correct code, then the fact that it doesn't return an array on error is a non-issue. In fact proper code doesn't even have to check @error. Proper code would resemble:

Local $a = _FileListToArray()
For $i = 1 To UBound($a) - 1
