each command needs to be passed parameters. names and types of parameters depend on 
command. for example if you need to pass some parameter to some command do like the following:

context.setValue("datasource", "#name, value\n\"name1\", \"value1\"");
or
context.setValue("datasource", "c:/jgenerator/data/somedatasource.txt");

and by the way command has to be attached to an Instance object by setting instance on the 
command and by setting command on the instance. don't ask ahy it's done this way, the 
desing was pretty much dictated by Macromedia Generator architecture and the way it worked.

it's all "documented" in .def files (<jgenerator>/ext/templates/) and in corresponding 
chapters in Macromedia Generator documentation.
