Uff....
After a longish discussion with Detlev we came up with a new proposal, which hopefully is acceptable to all. We agreed that a command name like "clearenv" or "scrubenv" or similar (which doesn't require any arguments) might be too dangerous for the unexperienced user why randomly types commands "just to see what happens". For example, even if you type "erase" it will not do any damage because arguments are missing - but "erase all" will blow away most of your flash content without asking.
So the idea is to call the new command "environment" (or short "env"); usage would be then:
=> env clear
to clear the envrionment (except read-only variables); thsi also allows for pretty useful additional functionality like this:
=> env default
This would be a very nice feature. With this command no knowledge is needed in which sector(s) the environment is stored. This would be very convenient in our production or service department, because all our different boards could be reseted to a known state with the same command.
to reset the environment to the (compiled in) default settings.
One might even consider something like
=> env clear all
to blow away the whole env, including the read-only variables.
Would that be acceptable to everybody?
No objections!
