Grammar of Messages 
This section describes the grammar to send program messages via GPIB. 
Program messages are messages that the user sends to the instrument 
from the external controller to control the instrument. A program message 
consists of 1 or more commands and their necessary parameters. 
Upper/lower case sensitivity 
Upper/lower case insensitive. 
Program message terminator 
A program message must be terminated with one of the 3 program 
message terminators: <new line>, <^END>, or <new line><^END>. 
<^END> indicates that EOI on the GPIB interface becomes active at the 
instant when the immediately previous data byte is sent. For example, the 
OUTPUT command of HTBasic automatically sends the message terminator 
after the last data byte.
