Writing an efficient array operation in IDL [message #74839]

Dear ALL,

Suppose, I have to create an output array B filled with value 8 as
follows, from the input 5x5 array A.

A = 0 0 4 0 0
0 4 0 4 0
4 0 0 0 4
0 4 0 4 0
0 0 4 0 0

B = 0 0 8 0 0
0 8 8 8 0
8 8 8 8 8
0 8 8 8 0
0 0 8 0 0

The logic is to fill the whole region bounded by value 4 in the input
array, with the value 8 in the output array.
How i can do this efficiently in IDL, like using array operations?
I need to apply for a large sized array.
Thanks in advance..
