{"product_id":"9780387966434","title":"An APL Compiler","description":"\u003cp\u003ePresents the results of an investigation into the issues raised by the development of a compiler for APL, a very high level computer programming language. APL presents a number of novel problems for a compiler writer: weak variable typing, run time changes in variable shape, and a host of primitive operations. Through the integration of several recently developed compiler construction techniques, such as data flow analysis, and a novel and space efficient demand driven or lazy evaluation approach to code generation, the author has been able to produce a true compiler for the language while still maintaining the felxibility and ease that are the hallmarks of APL.\u003c\/p\u003e","brand":"Springer New York","offers":[{"title":"Default Title","offer_id":47020804505840,"sku":"9780387966434","price":129.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780387966434_p0.jpg?v=1763696155","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780387966434","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
