Alias Command
Group
Use the Alias commands to dene new commands as a sequence of standard
commands. You may nd this useful when repeatedly using the same commands
to perform ce
rtain tasks like setting up measurements.
Aliases are similar to macros but do not include the capability to substitute
parameters
into alias bodies. The alias mechanism obeys the following rules:
The alias name must consist of a valid IEEE488.2 message unit, which may
not appear
in a message preceded by a colon, comma, or a command or query
program header.
The alias
name may not appear in a message followed by a colon, comma,
or question mark.
An alias
name must be distinct from any keyword or keyword short form.
An alias name cannot be redened without rst being deleted using one of
the ali
as deletion functions.
Alias names do not appear in response messages.
