$+(P) [When three data are set]
Processing details
• Links the character string data designated by (S2) after the character string data designated by (S1) and stores the result
into the area starting with the device number designated by (D).
• When character strings are linked, the "00H" which indicates the end of character string data indicated by (S1), is ignored,
and the character string indicated by (S2) is appended to the last character of the (S1) 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.
Program example
• The following program links the character string stored from D10 to D12 with the character string "ABCD" when X0 is ON,
and stores them in the area starting from D100.
(S1): Data for linking or head number of the devices where the data for linking is stored (character string)
(S2): Data to be linked or head number of the devices where the data to be linked is stored (character string)
(D): Head number of the devices where the linking result will be stored (character string)
