  Quick Help:
     Convert Data Track Percentage To Servo Offset Count, v[Percentage]

  Description:
    This command converts the specified data track percentage to a servo offset count for
    the current target track.

  Input Parameters:

    0 - Data Track Percentage.
    
        This parameter specifies the data track percentage for which the servo offset
        count is to be displayed.  It is in units of 0.1% of the data track width.  If
        this parameter is not entered, the offset count between track centers will be
        displayed.  For drives that implement V2BAR, this number will vary with radial
        position.
    
          Type:    Signed 16-bit value
    
          Range:   0x8000 to 0x7FFF
    
          Default: 0x3e8 (1000 decimal or 100% offtrack)
    
  Output Data:


    If an error occurred, the following information will be displayed.
    
          "DiagError aaaaaaaa"
    
       where
    
          aaaaaaaa is the Diagnostic Error Code
    
    If no error occurred, the Servo Offset Count Data will be displayed as follows.
    
          "Phy Cyl cccccccc Log Hd d Data Track Percentage eeee Servo Offset Count ffff Data Track Width wwww"
    
       where
    
          cccccccc is the physical cylinder address
    
          d        is the logical head address
    
          eeee     is the data track percentage
    
          ffff     is the servo offset count that will move the head offtrack by the specified
                   percentage on the specified track.
    
          wwww     is the width of a data track, in units of servo position. Q14 scaling, so
                   0x4000 is the width of a data track at nominal TPI (before VTPI and warping)
    
  Revision History:

    0001.0000   Initial revision.
    0002.0000   Changed to use Q14 servo count, instead of old servo offset count.
                Output also changed to include data track width in Q14 servo counts.
    0011.0000   Combined the PSG Diagnostic Error Codes (PSGDEC) and the Diagnostic External
                Test Service Error Codes (DETSEC) into a single set of Diagnostic Error Codes
                (DiagError).
