During the last fifteen years I have seen articles stating that COBOL will become a dead language. What did these writers expect compa-nies to do with the billions of lines of COBOL code that exist? Did they expect companies to retrain the hundreds of thousands of pro-grammers that were using COBOL? With IBM's introduction of COBOL II in 1984, COBOL/370 in 1992 and the inclusion of COBOL as a supported language of Systems Application Architecture (SAA), it seems clear that COBOL is here to stay. Companies are spending tremendous amounts of money to convert their programs to these new standards. Eased program maintenance and features that take advantage of the most modern coding and hardware technology are the minimums expected from these new COBOL compilers
