SOFTWARE AND OPERATING ENVIRONMENT

GEORGE 3 This is an operating system used to carry out automatically many operating tasks, otherwise performed manually. It controls the file-store, checks user's budgets and performs scheduling i.e. makes it possible to perform several jobs, of various kinds, simultaneously Multi-access is also organized by GEORGE 3 which allows a number of teletypewriters to be connected to the central processor through a multiplexor on a time-sharing basis.

Compilation Macros These are available for the standard programming languages, FORTRAN, ALGOL and COBOL. Their main function is to compile a source program but in addition some of then will also consolidate semi-compiled programs and execute object programs. Five series of compilers are available: these in ascending order of complexity are S, P, J, Q and full series, providing facilities appropriate to each class of user.
