Thanks!

The second example did the trick (the first seems to loose the last  
part of the initial string). I had to modify the code a bit to make it  
work with Matlab too. Just for the record, this is it:

--------
 vstr = sprintf ('Cars suck\tMotorbikes too\tBicycles are way cool!');
 vcnt = 1;

 while (~isempty (vstr))
   [vres{vcnt}, vstr] = strtok (vstr, sprintf ('\t'));
   vcnt = vcnt + 1;
 end

 vres{end} = [vres{end}, vstr];
 vres
--------
