REMOTE CONTROL

A query is a simple or compound
command followed by a question
mark (?). A parameter (data) is
returned.
Two or more commands on the
same command line. Compound
commands are separated with
either a semi-colon (;) or a semi-
colon and a colon (;:).
A semi-colon is used to join two
related commands, with the
caveat that the last command
must begin at the last node of the
first command.
A semi-colon and colon are used
to combine two commands from
different nodes.
Note
(Further
explanation)
A semi-colon(;) is used to connect two commands. A
colon(:) at the start of a command indicates that the
command starts from the root node. The first
command can ignore that first colon. Any commands
after the first command (for compound commands)
that do not begin with a colon, must begin at the last
node of the first command.
