KDF9 was an early British computer designed and built by English Electric, later English Electric Leo Marconi, EELM, later still incorporated into ICL. It first came into service in 1964 and was still in use in 1980 in at least one installation.

Author's Introduction
ALGOL 60 is a programming language for describing numerical processes and has the unique advantage of international recognition as a common language. ALGOL »s inherent merits are the bases of its widening acceptance for both scientific and engineering applications. The power of its statements often surprises newcomers. Its conciseness avoids much of the tedium in other forms of programming, simplifies the programming of complex problems 9 and makes it an acceptable medium for solving the occasional problem. The use of conventional symbols of mathematics and the borrowing of ordinary English words to form ALGOL symbols helps to make an ALGOL program easy to read and understand. The ALGOL identifiers are much more easily recognised and distinguished by the human eye than the numerical storage representation of computer codes. These advantages » by making programming easier, also enable a program to be written in a shorter time and result in fewer mistakes.

Of particular value are the ALGOL programs and. procedures published throughout the world, which are immediately available to the user of the language. By their means he has access to the work of recognised experts in the field of numerical analysis and to a wider variety of computer programs and techniques than can be obtained by using one machine code only.
