AsString – memset()

Fills the memory area with specific values

nxt_adr = memset(adr(Dest),value,length)

I/O	Parameter	Data type	Description
IN	pDest	ANY (transferred as a pointer)	Address of destination memory
IN	value	USINT	Initialization value
IN	length	UDINT	Number of bytes to be initialized
OUT	nxt_adr	UDINT	Address of pDest (for cascading)
