comp Subsystem Command
beep Level 2
set Level 3
ng Parameter
The basic rules of the command tree are as follows.
Letter case (upper and lower) is ignored.
For example,
COMPARATOR:RESISTANCE = comparator: resistance
Spaces (_ used to indicate a space) must not be placed before and/or after the
colon (:).
For example,
comparator_:_resistance comparator: resistance
The command can be completely spelled out or in abbreviated.(The rules for
command abbreviation are described later in this section)
For example,
comparator: resistance = comp:res
The command header should be followed by a question mark (?) to generate a
query for that command.
For example,
comp:res?
The semicolon (;) can be used as a separator to execute multiple commands on
a single line. The multiple command rules are as follows.
Commands at the same level and in the same subsystem command group can
be separated by a semicolon (;) on a multiple command line.
For example,
comp: beep: set ng; vol low
To restart commands from the highest level, a semicolon (;) must be used as
the separator, and then a leading colon (:), which shows that the restarted
command is a command at the top of the command tree, must follow.
For example,
comp:beep:set ng; : comp:r 100e6
The common commands can restart only after a semicolon on a multiple
command line.
For example,
