Hi,

Yeah, that was the first thing that occurred to me too, but when you use STRING on a
non-byte input, all you get is the number as a string, rather than the ASCII byte code
converted to a string:

IDL> a = bindgen(2, 4) + 65B
IDL> b = string(a)
IDL> c = string(fix(a))
IDL> help, a, b, c
A BYTE = Array[2, 4]
B STRING = Array[4]
C STRING = Array[2, 4]
IDL> print, b
AB CD EF GH
IDL> print, c
65 66
67 68
69 70
71 72
