| indices = Search2d(array, x, y)
| s = Size(array, /Dimensions)
| cols = indices MOD s[0]
| rows = indices / s[0]
| radius = Sqrt( (cols - x)^2 + (rows - y)^2)
| goodPixels = Where(radius LT myCircleRadius)
| cols = cols[goodPixels]
| rows = rows[goodPixels]

That's looking much better. Slowly I get behind the tricks of IDL. In the
past I was coding only C, so I am used to write for loops when I wanted to
process all elements of an array. I've learned very much, thanks again.

Unfortunately there's one stupid question left:
How to determine cols, rows and frames for 3D space? :)

Mhh, maybe this was caused due to my social activities this weekend. J/K :)
