I'm surprised that the "string_len" dimension is the first dimension
in variable "band_name" because that is the outermost dimension (the
one that varies most slowly).  CDL uses the C convention: the outermost
dimension is the leftmost and the innermost dimension is the rightmost.
Based on the names of the dimensions, I would have thought the following
more appropriate:

    char band_name(bands, string_len) ;
