_ArraySwap2D?

[drlava]

Is there an efficient way of copying a whole array subset without using loops?

Say I have an array;

Dim $array[5][2000]

I want to copy the fith set of the first dimension to the fourth set:

$array[4]=$array[5]

or in matlab-like style,

$array(4,=$array(5,

without doing:

for $i=0 to 1999

$array[4][$i]=$array[5][$i]

next

thanks of you have the solution.

Hi,; no!

But if you are asking "has it been done" to be more efficient?; maybe;

my link in sig gives a vbs option which may be faster for big arrays; so you get

Ok, thanks for the reply, I'll gove it a try. Maybe this feature will eventually be hard-coded.
