<div>Dear Mr Stewart</div>

<div>You can define symbolic parameters (variables) in SCICOS.</div>
<div>In SCICOS, go to Diagram ->context. You will see a SCILAB dialog window, where you can define the variables.</div>
<div>For example. I define the variable R =9. Now, I can use, in differents blocks (like constants, gains, etc), the variable "R" instead of a numeric value.</div>
<div>You can modify the value of "R" before every simulation.</div>

made up of many super-blocks all the same. Each one represents 1 unit<br>of length of the transmission line and contain a resistor and inductor<br>in series and then a capacitor to ground. I then can connect a scope to<br>
different locations in the "line" and show my students how a pulse gets<br>deformed as it travels down the line, and show the reflected waves, etc.<br><br>I have a 25 unit line working, but now I want to change the resistor<br>
value, etc.<br><br>My question is:<br><br>How can I set it up so that I can change a "Global variable" that will<br>change all my resistors at the same time?<br><br>Doug Stewart<br><br><br><br></blockquote></div>
