BASIC environment ending with "run complete", and slashed 'O' characters?

[Paul Koning]

Apparently so.  The word from a CDC experts list is that the "run complete" message is not from BASIC itself (which is indeed a CDC product) but rather from the time sharing executive, called TELEX in KRONOS and early NOS, and IAF in later versions of NOS.

As for the slashed letter O, that's strange.  Certainly it is not CDC practice; the only place I ever ran into this is with IBM, I always considered it an example of IBM doing things the weird way.  So it sounds like whoever bought those Teletype machines had them configured in that non-standard way for some reason.  Normal, as far as I know, was slashed digit zero.

MECC is a U. Minnesota KRONOS/NOS system with a bunch of local mods, but BASIC and TELEX are both part of the base system as supplied by CDC.
