Defining a Sequence
A sequence defines a series of SCPI commands with an associated name.
When the sequence is first defined, the commands are compiled and then
stored in a compressed format in non-volatile memory. The following SCPI
commands by L4400 LXI instrument are allowed in a sequence definition (all
other commands will generate an error).
