In Burroughs, still sold as ClearPath MCP, to use applications compiled with unsafe code blocks (NEWP is one of the first systems languages with unsafe concept), the admin has to enable their execution in first place.

Until then the executables are tainted and will trigger an error instead of being executed.

Only the standard library, and OS system tools, as Trusted Computing Base, are excepted from this.

This is the whole point of systems security, everything is unsafe down to silicone, the whole point is reducing the amount of Trusted Computing Base that has to be manually validated and certified.
