function sb2sldly(blkname,in,fl,cod,timer)
%SB2SLDLY converts time delay blocks to SIMULINK.
%	SB2SLDLY(BLKNAME,IN,FL,COD,TIMER) converts a SystemBuild block
%       to a SIMULINK block.  BLKNAME is a string containing the name of
%       the block. The parameters are set up for this block based on the
%       SystemBuild file coding integer IN and real number FL.
%
%       COD is a three dimensional vector. The first element indicates
%       whether it is a continuous (0) or discrete (1) time system.
%       The second element indicates whether it does not need (0) or
%       does need (1) a mask. The third element indicates the
%       orientation of the block.
%
%       TIMER is designed for discrete time only. The first element of
%       TIMER is the sampling time. The second element is the initial time.

% in = [8, code1 code2, input, output, state,....
% state / output --> order of integer for each one
% if input > output --> resettable
%   (input - 1)/output - 1 = highest order resettable   
% This one works the same for continuous or discrete time systems.
