%	ext56chk.m	makes sure that the string are looking for is not longer than the
%	entire string being searched, returns 0 for "good_string" if not good or 1 if good
%	10-13-00

%	findstr returns the starting indices of ANY occurrences of the SHORTER of the two strings
%	in the LONGER and we want to be sure that it is ALWAYS finding the "check_string" within 
%	the "whole_string"

% 		FINDSTR Find one string within another.
%    		K = FINDSTR(S1,S2) returns the starting indices of any occurrences
%    		of the shorter of the two strings in the longer.
% 
%    		Examples
%        		s = 'How much wood would a woodchuck chuck?';
%        		findstr(s,'a')    returns  21
%        		findstr(s,'wood') returns  [10 23]
%        		findstr(s,'Wood') returns  []
%        		findstr(s,' ')    returns  [4 9 14 20 22 32]
