Certain features of the Supervisor as described in this manual are not yet implemented at all Atlas 1 installations. In particular STORE s1/s2 (sections 1.3.6 and 1.3.8) is not at the time of going to press available on the London University Atlas 1, and the Supervisor printing at the end of output stream 0 (section 3.3.) is not yet uniform between installations.
There are also certain operational differences between installations which have not been mentioned in this manual. For these reasons it is recommended that the installation concerned be consulted on points of doubt.
