The year 2000 is almost here and anyone involved with the manufacture, programming or use of computers is concerned. Unless computers are re-programmed to take into account of the two zeros at the end of 2000, computers, computer chips, etc. could and will stop at the end of century. In order to re-program, computer programmers need to program the old mainframes, some PCs, and chips in Cobol. Cobol programmers are in great demand, but some need to "brush up" their Cobol skills. Many more computer programmers will need to learn Cobol in order to satisfy the demand for Year 2000 compliance. This book will cover all the main skills needed for all this re-programming: Cobol (at present covers 50-60% mainframes); PL/1 (at present covers 30% mainframes); and RPG (at present covers 10% mainframes).
