function theResult = ncsetstr(x)

% ncsetstr -- SETSTR for NetCDF character data.
%  ncsetstr(x) converts values x to unsigned-characters
%   in the range 0:255, for use by Matlab.  Beginning
%   with Version-6, Matlab characters must be non-negative,
%   whereas the sign of NetCDF "char" is undefined.
