It is frequently desirable to display the results of computation in a graphical form. This is often done through the use of special hardware such as digital X,Y-plotters. Programmed graphical output for standard printers is preferable in several ...

The initial version of IPL-V for the Philco 2000 has been completed and is now operating on the computer. This model, IPLT-1, contains the loader, interpreter, output, housekeeping functions, and some of the primitives of the 7090 version.

This system ...

One school of thought for future computer systems involves the use of large computer complexes, time-shared among many users. Because internal computer speeds are so much greater than communication speeds with the outside world, machine efficiency ...

ALGOL 60 is defined partly by formal mechanisms of phrase structure grammar, partly by informally stated restrictions. It is shown that no formal mechanisms of the type used are sufficient to define ALGOL 60.

Several of the computer languages that are oriented toward problems in symbol manipulation use a list type of memory organization.¹ The advantages of such a memory organization have been discussed elsewhere and will not be repeated here. The purpose of ...
