Alias Command Group
Use the Alias commands to define new commands as a sequence of standard
commands. You may find this useful when repeatedly using the same commands
to perform certain tasks like setting up measurements.
Aliases are similar to macros but do not include the capability to substitute
parameters into alias bodies. To use Alias commands, first define the alias, then
turn on the alias state.
The alias mechanism obeys the following rules:
