\"Gr\u00fcnes
\nCoJaC is our tool for conver\u00adting histo\u00adri\u00adcal COBOL appli\u00adca\u00adti\u00adons to modern Java soluti\u00adons. CoJaC genera\u00adtes maintainable and high-perfor\u00ad\u00admance Java code which is seman\u00adti\u00adcally equiva\u00adlent to the COBOL code.
\nDuring conver\u00adsion, the tool achie\u00adves an automa\u00adtion level of 95\u201399 %. CoJaC combi\u00adnes scien\u00adti\u00adfic know-how in compi\u00adler construc\u00adtion with core compe\u00adtency resul\u00adting from successful migration projects.<\/p>\n<\/div>\n\t\t<\/div><\/div><\/div><\/div><\/div><\/div><\/div>

CoJaC TECHNOLOGY<\/h2>\n

For complex compi\u00adling proces\u00adses, the use of speci\u00adfic conver\u00adsion tools, so-called trans\u00adla\u00adtors, is neces\u00adsary. Trans\u00adla\u00adtors work by analogy with a compi\u00adler which, via diffe\u00adrent inter\u00adme\u00addiate stages, compi\u00adles source program\u00admes to execu\u00adta\u00adble target code.<\/p>\n

CoJaC is a trans\u00adla\u00adtor for conver\u00adting histo\u00adri\u00adcal COBOL appli\u00adca\u00adti\u00adons to modern Java soluti\u00adons. For the requi\u00adre\u00adments of language conver\u00adsion, we have further develo\u00adped the general compi\u00adler model into a trans\u00adla\u00adtor model:<\/p>\n
