8 Function Instructions

8.4 Data Transfer Instructions

 Processing will be performed without error even in cases where the range for the devices storing the character string data

to be transferred ((S) to (S+n)) overlaps with the range of the devices which will store the character string data after it has

been transferred ((D) to (D+n)). The following occurs when the character string that had been stored from (D10) to (D13) is

transferred to (D11) to (D14).

 If the NULL code "00H" is stored at the lower bytes of (S+n), the NULL code "00H" will be stored at both the upper bytes

and the lower bytes of (D+n).

Upper byte is not

transferred.

 When 2-byte data such as Japanese characters (Kanji) is designated by (S), the data is converted to shift JIS code. If the

$MOV instruction is executed, the upper bytes and lower bytes are stored in (D) in the opposite order.

 For the operation when the character string enclosed in double quotes is specified by (S), refer to "6.3.5 Character String

 Operation errors

 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.

- The NULL code "00H" does not exist in the relevant device range starting from the device number designated by (S).

(Error code: 82)

- There are not enough points from the device number designated by (D) to the last device number of the relevant device

to store the designated character string. (Error code: 82)

- The character string of S is longer than 255 characters. (Error code: 82)
