** The function below is used in moving data.  This function is

** called in the main command loop parser of the monitor.  The

** parameters passed to this function are:

**

** token - This is an array of pointers to strings.  Each string

**         referenced by this array is a "token" of the user's

**         input, translated to lower case.

**

** token_count - This is the number of items in the token array.

**

** This function reduces the tokens to three parameters:

** the start address and the end address of the move and the

** target address of the move.
