I need to trap an array error when element is missing

[PerryRaptor 1]

I use a single dimension array to capture user input in an edit box, I use StringSplit($ChatBox1, ' ', 1) triggering on a space ' ' to as the delimiter.

Sometimes there will not be an element 3, array[3] and I need some way of capturing this error allowing the script to move on.

IF array[3] <doesn't exist expression> then array[3] = "parameter is missing...try again"

I need help with coding the <doesn't exist expression>

Perhaps the @error macros may help. You can check to see if an error occurs and have it output what you want.

project is too big for the @error macro

I think I need something along the lines of:

If not Ubound($Array) == 4 then $array[3] = "parameter is missing"

Do
    $input = InputBox('Test', 'Enter 3 characters')
    $result = StringSplit(StringStripWS($input, 8), '')
    If UBound($result) - 1 <> 3 Then MsgBox(0, '', 'Too few or too many characters.  Try again.')
Until UBound($result) - 1 = 3

MsgBox(0, '', 'success')

Or, say you have several arrays, and for each array you must do something to it, then you would do something like this:

For $i = 1 To Ubound($array)-1
    ;whatever you want to do to each array
    ;$array[$i] = each array
Next

Just thought it would be useful for you to know.
