function outstr = yhzappstr(instr,app)
% APPSTR  Append string to callback string.
%   STR1 = APPSTR(STR,APP) appends the string APP to the string
%   STR.  If STR has greater than length 0, and no semicolon is
%   found in suffix (at the end of STR followed by spaces), a 
%   comma is appended first.
