XA final parameter in a combination of
escape sequences.
XA single escape sequence.
xA non-final parameter linking a series of

The binary data is optional eight-bit data which is downloaded
immediately after an escape sequence. The length of the binary
data in bytes is normally specified by the preceding numeric
variable.

Combining escape sequences
Escape sequences may be written in separate strings (figure 3-3)
or linked together for simplicity (figure 3-4). Commands with
variables may be combined if the variable sequence character and
the group character are the same for each command. The
following rules apply:
• The escape character, the variable sequence character, and
the group character are omitted from all but the first escape
sequence when sequences are combined.
