% Turing is a "sequential" programming language.
% So is Pascal, FORTRAN, C, BASIC, etc.

% This means that each instruction executed one
% after another, in sequence.  The same holds
% for loops.

% In the following, for example,

var a,b: real

a := 3.4
b := a + 1.0

put a
put b
put a+b

% the assignment and "put" statements are
% ALWAYS executed exactly in the order given.


% What is the output of this program?

% Examples of non-sequential programming:
%	* spread sheets
%	* parallel programming languages
%	* window systems software
