## @deftypefn {Function File} {} namelengthmax ()
## Returns the matlab compatible maximum variable name length. Octave is
## capable of storing strings up to 
## @iftex
## @tex
## $2^{31} - 1$
## @end tex
## @end iftext
## @ifnottex
## @code{2 ^ 31 - 1}
## @end ifnottex
## in length. However for matlab compatibility all variable, function
## and structure field names should be shorter than the length supplied by
## @code{namelengthmax}. In particular variables stored to a matlab file
## format will have their names truncated to this length.
## @end deftypefn

function n = namelengthmax ()
  n = 63;
