This can be solved with a little trick I posted awhile back (some time
after a long thread about indices). The trick is to index an extra
dimension.

Example:

IDL> array = bindgen(16,16,5)
IDL> index = indgen(5)
IDL> x = [0,1,2]
IDL> y = [8,9,10,11]

IDL> result = array[x, y, index, 0]

IDL> help,result
RESULT BYTE = Array[3, 4, 5]

IDL> print,result[*,*,0]
128 129 130
144 145 146
160 161 162
176 177 178

You could also do
IDL> result = array[x, y, *, 0]

Henry.
