Use the seek command. 
seek HANDLE,0,0;

[download]
you mileage may vary if trying to seek on streams or pipes (like STDIN).

    Just to clarify lhoward's answer:
    The second parameter for seek is a position, the third parameter is what the position is relative to:

    0 Relative to the beginning of the file.
    1 Relative to the current position.
    2 Relative to the end of the file.

    So, 

      seek HANDLE,0,0
    means to move to index 0 relative to the beginning of the file.
