Is there a way to prevent a variable, let's say a, to be incidentally deleted, for example in a program ?

Only by storing it in port 2. You can't prevent the user from erasing it, but you can recover it using Flash tools if that happens. Another solution is to make it NULL-named, you won't be able to purge it but then you can't recall it by normal procedures either.
On the other hand, newRPL does have that feature, you can lock/unlock any variable, trying to STO anything throws an error saying that the variable is read-only.
