  • Brandeis, K. E. review of Heijn et al 1960 view details Abstract: The paper gives a brief description of the Philips Automatic Sequence Calculator, PASCAL. It is divided into three sections description of the machine, a discussion of some of the programming features, and a description of constructional details. The most interesting features of the machine are: 1) the speeding up arrangements for the carry in the adder and the multiple way switch; 2) the two versions for modification of instructions; 3) the count and repeat instructions and the two types of link instructions for going to subroutines; 4) the jump instructions on the result of an earlier comparison; 5) the address-interpretation bit and the indicator word; and 6) the simultaneous data transfer in both directions between core memory and drum or tape while computations go on. Many original and new ideas have been realized in this machine. The paper is very interesting for people working in the field of machine-organization.
