10.3 Prefix 'dup' - repeat instructions DB/DW/DD

-------------------------------------------------

The repeat prefix 'dup' can be used with assembler instructions DB, DW

or DD, as follows:

$DW NUMREP dup VALTOREP

NUMREP - number of repeats of instruction DW

VALTOREP - value to repeat NUMREP times

In contrast to the analogous prefix in assembler, the repeated value

cannot be placed in brackets.
