A proposal for input-output conventions in ALGOL 60
May 1964 - Vol. 7 No. 5
Features
The ALGOL 60 language as first defined made no explicit reference to input and output processes. Such processes appeared to be quite dependent on the computer used, and…
On declaring arbitrarily coded alphabets
The inability of existing programming languages to handle character strings from more than one or two alphabets is mentioned and a scheme for declaring additional…
An experiment in a user-oriented computer system
A version of a software-hardware system for the purpose of facilitating the programming and analysis of well-formulated problems is described. A modified Flexowriter is…
A fast procedure for generating exponential random variables
A very fast method for generating exponential random variables in a digital computer is outlined.
An improved equivalence algorithm
An algorithm for assigning storage on the basis of EQUIVALENCE, DIMENSION and COMMON declarations is presented. The algorithm is based on a tree structure, and has…
Computer-usage accounting for generalized time-sharing systems
The current development of general time-sharing systems requires a revision of accounting procedures for computer usage. Since time-sharing system users operate…
A method for comparing the internal operating speeds of computers
First, a table of frequencies of various types of operations is prepared based on experience in similar applications or, perhaps, on actual counts if these are available.…
Expand, a system for input card replication
In an effort to reduce the volume of card handling at our installation, our operating system [1] was modified to include an EXPAND feature. The function of EXPAND is to…
The FORTRAN II CHAIN feature on the 7090 can be used to save card-to-tape time, loading time, and to provide a convenient method for storing and transporting producting…
Picture generation with a standard line printer
A method is described for producing gray-toned pictures on a line printer by utilizing the different degrees of blackness of standard print characters. Gray scales with…
