In the context of programs and scripts, a system is an abstract term mainly referring to the instrumentation for which the program was intended. This is not meant to be the computer where it runs. But in some cases, as for example a datalogger program, the former and the latter definition overlap. In this case, the system would be the datalogger itself, say DL (data logger). Since the system is in no measurement variable, a small “i” must be added as a prefix.
The systemname should be used for e.g. Campbell logger station name, computer name …
When using the Systemname as computer name there are some restrictionsdepending of the OS. With a Linux system (and almost all others) it is not possible to use _ (underline) character in the name. Therefore use dash (-) instead.
