Refer to § 5.2.1.1.1 for a detailed description of the BCCB octet.
Use of the Y,X parameters is as defined in § 5.2.1.2. The Cursor Number bits in the BCCB specify the
cursor to be affected.

For this command, the Return Cursor bit in the BCCB octet has no meaning.
5.2.1.6 Shift Display Field Left (05)
This command has two possible formats, as shown in Figure 38/MTS22-C.
This command shall be used by the system to shift a terminal's display one character position to the left and
add a new character to the right. The cursor will be returned to the position it occupied before the operation
was executed. The field to be shifted must be a subset of one line on the
display.

Shift Display Field Left command format
The Buffer Number parameter in the BCCB (see § 5.2.1.1.1) specifies the internal buffer to which the
operation applies.
Note -
If the Buffer Number value indicates all buffers, this command shall be ignored by the terminal.
The Y,X octets specify the leftmost character position of the affected string. The range of
values for the Y,X octets is defined in § 5.2.1.2.
The FL octet specifies the field length of the character string to be shifted. The value of the FL octet may
occupy the range 0 to 255 (decimal).
The C octet specifies the character to be inserted. The character shall be encoded in accordance with the
extended ASCII format (see § 5.2.1.1.9).
Note -
As an example, given the field ABCDEF, the message Shift Display Field Left (+ Z) will result in
the display BCDEFZ.
5.2.1.7 Shift Display Field Right (06)
The command formats and codings shall be as defined in § 5.2.1.6.
