CCS: Scripting Console - output to a text file

Tool/software: Code Composer Studio

I am using a .js file to automate a simple test.  The test changes based on some configuration data which is pulled in via a pound define based on the test -

i.e.

#if TEST == 1
    #define <parameters>
     .....
#elif TEST == 2
    #define <parameters>
   ......
etc..

I'd like to be able to fprintf to a .h file to define which test before rebuilding the project.  i.e. myRunTest 4 would write to the .h file:

#define TEST 4

I am unable to find a way to print to a file except to print to a log in xml format.   Am I missing a way to do this?
