Copying character strings

QUESTION:
How can I copy strings simply?

ANSWER:
Since the system function SFC 20 ("BLKMOV") does not support any character strings, you can proceed as follows:

Using the function FC 2  ("CONCAT") from the IEC functions of the standard library, you actually join two strings. If you leave the second string empty, then only the first string is copied to the desired location (see Figure 1).
