You have a ';' in comment and a ',' varname which is why it doesn't work
like you expect.  You will be better off using {} rather than [] for an 
array
of strings because you can then use x.comment{i} rather than
deblank(x.comment(i,:)) to reference them.  You need the deblank
for [] because a character matrix must be rectangular.  You don't
need it for {} because a vector of values can contain character vectors
of different lengths.
