* xxxx = a 4-byte buffer address, 0 to 1919, right-adjusted, zero-filled
y = character to be repeated
ttt = scanner order designator
a = an attribute byte
** /Sttt applies only to the 6400, 5055, 59XX, 17XX, 11XX.

Terminal orders may be included in each 3270 data stream command,
either alone or intermixed with display data. Terminal orders are executed
sequentially, and only after the complete data stream has been received by
the terminal and checked for errors. Orders are not stored in the display
buffer with other data in the data stream. For the asynchronous data
stream, they are added to the data stream following a "/" character.
Buffer control orders position, define, and format data being written into
the buffer. They also erase selected unprotected data in the buffer and
reposition the cursor address. The following table lists the orders.

The following pages describe buffer control orders executed sequentially at
the selected terminal after the complete data stream was received by the
station and checked for data integrity. These orders are not stored in the
display buffer.
Most of the buffer control orders position, define, and format data written
into the buffer, erase selected unprotected data in the buffer, and reposi-
tion the cursor address. The Scanner order is an extension of the 3270
data stream and is not supported by the 3278 Model 2.
