The list of commands that you pass to submitjob is a set of query handlers.

Those queryhandlers can execute FlexScript.

For example, in the example submitjob in the documentation, it calls a nodefunction in tools called "setupscript" which can execute FlexScript. It also calls settable and passes the string "hello," which could be FlexScript.

Just following that example, you could set the FlexScript code using settable and then execute it using toolsnodefunction.

Alternatively, you could create a custom query handler in your model that executes a string of FlexScript that is passed to it directly. You aren't limited to using only the query handlers already defined in the main tree.
