I dont understand !!, cant I redim my $array[5,1] to $array[6,1] ?

dim $array[3]

$array[0] = 0,'a'
$array[1] = 1,'a'
$array[2] = 0,'b'
$array[3] = 0,'c'

? $array[0][1]

redim preserve $array[4]
 $array[4] = 2,'a'

? $array[4][0]
? $array[4][1]

as a rule of thumb, always redimension the LAST dimemsion

If the Preserve keyword is specified, each dimension except for the rightmost one must be the same as those of the existing array.
