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.
