Easiest way to replace item in array...

Is there a fast and efficient way to replace an item in a one dimensional array? or do I need to loop through the items and just replace the item that way?

If you are looking for a fast way to determine the INDEX of an item in an array...then No.  You have to loop over it to find the right spot that you want to overwrite.

If you need a fast way to do LOOKUPS then use a Collection instead of an Array.

Sorry, was jim horns answer what you were looking for?

If the array is sorted, then a binary tree search is a good way of quickly finding an item

To remove an item is harder

To swap an Item with another part of the array requires a temporary variable of the same type

tmpString = aitem(2)
aitem(2) = aitem(4)
aitem(4) = tmpString

Or are none of these the type of thing you are asking about?
Or if you want to replace all items of a certain value...

That either requires a loop (easy & fast on small arrays)
or a binary search on a sorted array, followed by a loop (harder but very fast for large arrays)
