in thread Clearing Array Values

Yeah, knew that on the @ and $ thing there, used the @ so the writing was clearer.. I tested out your two thing and came up with a parallel <sp? its late> problem.

$array =(); print $#array, "\n"; results in -1 as it should be since the array has no values any longer and is a cleared array.

$array = undef; print $#array, "\n"; results in 0; which is not a cleared array, its an array with one value, and in this programs case would have resulted in the same bug, since the looping would have then started at the $array1 value instead of $array[0] value.

Ah. the things I think are important on a Friday night.

Anyway, thanks for the comments, always more than one way to do a thing.

    undef @array and @array = undef are not the same thing.

    You seem to be confused. I did not mean that $array should be used instead of @array. @array is definately correct if you are not selecting an indiviual element...
