Linking character strings
$+(P) [When two data are set]
Processing details
• Links the character string data designated by (S) after the character string data designated by (D) and stores the result into
the area starting with the device number designated by (D).
• The object of character string data is that character string data stored from device numbers designated at (D) and (S) to
that stored at "00H".
• When character strings are linked, the "00H", which indicates the end of character string data designated at (D), is ignored,
and the character string designated at (S) is appended to the last character of the (D) string.
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
(S): Data for linking or head number of the devices where the data for linking is stored (character string)
(D): Head number of the devices where the data to be linked is stored (character string)
