Character string transfer
$MOV(P)
Processing details
• Transfers the character string data designated by (S) to the area starting from the device designated by (D).
• The character string data enclosed in " (double quotes) specified by (S) or the string from the device number to the number
for the device storing the NULL code "00H" is transferred all at once.
• Processing will be performed without error even in cases where the range for the devices storing the character 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 data that had been stored from D10 to D13 is
transferred to D11 to D14:
• If the NULL code "00H" is stored at lower bytes of (S)+n, the NULL code "00H" will be stored at both the upper bytes and
lower bytes of (D)+n.
• For the operation to be performed when the character string data enclosed in double quotes is specified by (S), refer to
Page 91 Using character string data.
(S): Character string to be transferred (maximum string length: 32 characters) or head number of the devices where the character string to be transferred is
stored (character string)
(D): Head number of the devices where the transferred character string will be stored (character string)
