pMem : DINT; (* memory address *)
bValue : DINT; (* value *)
dwSize : DINT; (* number of bytes *)
END_VAR
dwSize bytes after memory address pMem with a value bValue will be
written.

FUNCTION MOVESWAPPED: DINT
VAR_INPUT
pDestination : DINT; (* memory address *)
pSource : DINT; (* memory address *)
sDescstring : STRING(255); (* Data description string *)
END_VAR
The function copies data from the memory address pDestination to the
memory address pSource. The data are copied swapped in accordance with
the descriptor string defined.
The descriptor string has the following format:
<number><type><number><type>...
Number is a decimal number and defines then data quantity for the
following type.
Type is a lower−case letter describing the size of the data type as follows:
Type Codesys data type Size
B BYTE 8 Bit
W BOOL, WORD, INT 16 Bit
D DWORD, DINT, REAL 32 Bit
