[Character-string memory table display example]

To display the characters in order, allocate the characters as follows.

“A” = 41H, “B” = 42H Start

“C”￿= 43H, “D”= 44H Start + 1 “E” = 45H, “F” = 46H Start + 2 “G” = 47H, “H”= 48H Start + 3

“ABCDEFGH”

Character allocation bestriding two words.

Provided the order is correct, it is possible to assign two digits each of a four-digit character code to successive words.

[Example of character code bestriding words]

“A” = 41H, “B” = 42H			Start
“C” = 43H			Start + 1
“	” = EB9FH		Start + 2
“		” = EBA0H	Start + 3

“D” = 44H

Reference Characters with 8-bit codes (00 to 1FH) are displayed on the screen as a one-byte space (20H). 00H is converted to 20H.

6-2-2 Changing Displayed Numerals or Character Strings

(Changing the Contents of Allocated Words....Direct Specification)

The following describes the procedure to change displayed numerals or character -strings by changing the contents of the allocated words.

Reference Numerals and character-strings can be changed also by making a copy of the memory tables. Refer to “Copying the memory table” explained later.

To change the numerals or character-strings displayed on the NT600S, make changes with the numeral or character-string memory table. To make changes with the numeral or character-string memory table of the NT600S, change the con- tents of words by the PC.
