 **

 **       This code provides "fill" routines to fill memory and

 **       registers.  Data may be set as words (32 bit), half-words (16

 **       bit), bytes (8 bit), float (32 bit floating point) or double

 **       (64 bit floating point).

 **

 **       Since registers are 32 bits long, the fill byte and fill half

 **       commands will only be permitted for memory accesses.

** The function below is used in filling 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 four parameters:

** the start address of the fill, the end address ofthe fill and

** and the data to be filled in this range.  This data

** is one of the "temp_" variables.
