Semicolon
n
A semicolon separates two commands in the same message without
changing the current path.
White space characters, such as <tab> and <space>, are generally
ignored. There are two important exceptions. White space inside a
keyword, such as :FREq uency, is not allowed. You must use white
space to separate parameters from commands. For example, the
<space> between LEVel and 6.2 in the command :POWer : LEVel
6.2 is mandatory. White space does not affect the current path.
If a command requires more than one parameter, you must
separate adjacent parameters using a comma. Commas do not
affect the current path.
Common commands, such as *RST, are not part of any subsystem.
An instrument interprets them in the same way, regardless of the
current path setting.
Figure l-26 shows examples of how to use the colon and semicolon to
navigate efficiently through the command tree.
