WREPLACE (FUN)

FUNCTION WREPLACE : WSTRING(255)

Replaces L wcharacters of STR1 by STR2, starting at the POS-th wcharacter position and returns the new string. POS = 1 is the first character.

Note

The current implementation is unfortunately not correct for the case P=0. The implementation cannot be changed for compatibility reasons.

If P=0 is used, the parameter L is internally reduced by one!

It is generally recommended to use values in the range specified by IEC 61131-3. The smallest value for P is specified there as 1.
