- <h4>Scripting support provided in the Executive</h4>
-
- <p>There is simple scripting support provided in the FGFDMExec
- class. Commands are specified using the <u>Simple Scripting
- Directives for JSBSim</u> (SSDJ). The script file is in XML
- format. A test condition (or conditions) can be set up in the
- script and when the condition evaluates to true, the specified
- action[s] is/are taken. A test condition can be <em>persistent</em>,
- meaning that if a test condition evaluates to true, then passes
- and evaluates to false, the condition is reset and may again be
- triggered. When the set of tests evaluates to true for a given
- condition, an item may be set to another value. This value might
- be a boolean, a value, or a delta value, and the change from the
- current value to the new value can be either via a step function,
- a ramp, or an exponential approach. The speed of a ramp or
- approach is specified via the time constant. Here is the format
- of the script file:</p>
-
- <pre><strong><?xml version="1.0"?>
- <runscript name="C172-01A">
-
- <!--
- This run is for testing C172 runs
- -->

- </when>
- </run>
-

- <p>The first line must always be present. The second line
- identifies this file as a script file, and gives a descriptive
- name to the script file. Comments are next, delineated by the

- comes the "run" section, where the conditions are
- described in "when" clauses.</p>
+ When an aircraft model is loaded the config file is parsed and for each of the
