*
*    Do whatever has to be done on a per frame basis:
*
*   * Update frame and block counters
*
*   * Set test data level of detail for particular frames:
*     Level  Meaning
*       -1     Vary detail level by frame 
*        0     No data file generated
*        1     Processing statistics only
*        2     Coded parameters for each frame
*        3     Scalar variables and RC's
*        4     Vectors and matrices
*        5     Synthesis buffers
*        6     Analysis buffers
*
*   To use variable detail level, create a file 'TESTDATA.DAT' with lines
*   containing < starting frame, ending frame, detail level > for each
*   range of interest.  If ending frame = 0, the specified detail level
*   will be used when not within any explicitly specified range.
