using get_Param inside an S-function

function [sys]= mdlOutputs(t,x,u,flag,Label)

 tSTOP = get_param('Model','StopTime');
 if(tSTOP == (1000*ceil(t/1000)))
   fclose(FID);t
 end
 sys = [];
 return;
end

tSTOP is not seen inside the 'if' loop. The value of 't' does not get printed out. If I replace tSTOP with the numerical value of tTSOP it works fine. Any help is appreciated.

How do I convert the output of get_Param to make it suitable for use in 'if' loop. Using 'round' did not work.

[Aswartha Narayana]

using str2num did work; the output of get_param here appears to be a string.

[Walter Roberson]

There is no such thing as an if loop.

[Aswartha Narayana]

use str2num to convert the character string that results from get_param() into a number. The number is then suitable for use in 'if' loop.

What you are doing (closing the file) should be done in mdlTerminate!
