Outline of operation
● This instruction stores the storage area size specified by [S1] in [D].
● The character constant specified by [S2] is converted to ASCII code, the number of
characters (1 word) is stored in [D+1], and the character data converted to ASCII is stored in
subsequent areas in sequence from the low byte.
● Character constants should be put between "" (double quotations) for specification.
● From 0 to 256 characters can be specified for a character constant.
● When there are double quotation marks enclosing no character, it is recognized as a NULL
character
● When setting, NULL (00) is not added to the end of characters.
