%      boundary) is selected.
%   Input the k boundary values: The same set of boundary values will be used 
%      for all the test statistics. If 2-sided test is specified, then the
%      negative of the values will be used as lower boundary.

%
%   Input the number of intervals to specify the baseline survival function: 
%      Up to nl=20 are allowed.

5
%   The survival function at 0  has been set to 1.
%   Input the J survival probabilities at the points specified in the last

%   source code dsss1.f. The initial m is set  to be 7000 
3 300 500
%
%   Input the desired power. The program will try to find the appropriate
%   accrual rate for the desired power. Please read the last few lines of the
%   output file to see if the desired power has been reached. Otherwise we
%   may either modify the bounds on the accrual rate (previous input) or the
%   desired power in the following line.

%
%   Input the alternative survival function. 
%   Input the number of intervals (>=1) to specify the alternative survival
%      function: Up to 20 are allowed.

%      survival function to be specified in the same way as the baseline 
%      survival function, input 1. If you want the alternative survival 
%      function to be specified by hazard ratio, input 2. Type 1 or 2:
