5.1Read from Buffer Memory ⋅ ⋅ ⋅ GET, GETP

<Format>	execution condition
	for GET
		GET n1 n2	D	n3
Format	Descriptions				Available Data Type
n1	The slot No. where a special module is mounted				Integer
n2	Head address of the special module buffer memories from which				Integer
	the data will be read.
D	Head address of the device to store the data read.				M,P,K,J,T,C,D,#D
n3	Number of data to be read .				Integer

<The difference between GET and GETP>

GET: Always executed if the execution condition turns on.(

GETP : Executed if the execution condition is triggered. (
