I don't think PULSE is what you need to use. At t=0, "TDS Switch"=0 (which is the start time of the pulse, so it will trigger at t=0).
Try looking at the SAMPLE IF TRUE function, that might do what you want.

The easiest way is to change the noise seed for the random number generation and do lots of batch runs (see http://www.vensim.com/documentation/html/25670.htm for details on how to automate this process using a command file). Basically change the noise seed and save each run under a different name. ...

I have asked for clarification (I would expect the same results as you). If you are still using our external function library, you could use the SORT ASCEND/DESCEND funciotns. That should work as expected (not zero based though). Syntax is something like SORT ASCEND 1D ( vector, size of vector, trig...

Best thing is to go through the tutorial.
If you go to the following link, and then go to the "User guide", chapter 17, that covers subscripts.

[ADMIN]Response via e-mail.[ADMIN] This is how Sable/Vensim works. When you are in Vensim and do a run, all constants etc return to their previous values. This is exactly how Sable works as well. To get around the problem, simply write a CIN file before the run is done, and read it immediately after...

Hello, Encryption is only possible when a redistribution kit has been purchased. The kit allows models to be encrypted before distribution to protect the code within them. There is no way of protecting the model if only using runtime versions of the DLL. One more small bit of info, you need to purch...

Hello and welcome to the forum. It is very simple to do what you want. Look at the DELAY FIXED function in the Vensim help system. You would have the equation Z = X + Y and X = DELAY FIXED ( Z , TIME STEP , 0 ) You might need to check the syntax, but it should do what you want. Z takes on the value ...
