floating point control registers can be accessed only in scope 0 Facility: DEBUG, VMS Debugger Explanation: An attempt was made to reference a floating point control register from a scope other than scope 0. DEBUG will not accept a command which specifies any other scope for a floating point control register. User Action: If the current scope has been set to a scope other than scope 0 (using the SET SCOPE command), use an explicit 0\pathname to access the floating point control register.
