Its user language, originally intended as a special-purpose non-procedural language, was designed to capture the style and succinctness of common mathematical notations, and to serve as a useful, effective tool for on-line problem solving. This paper describes extensions to the language which enable it to serve also as a high-level programming language, both for the formal description of mathematical algorithms and their efficient implementation.<\/jats:p>","DOI":"10.1145\/1086830.1086834","type":"journal-article","created":{"date-parts":[[2007,1,17]],"date-time":"2007-01-17T18:32:02Z","timestamp":1169058722000},"page":"20-30","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["The SCRATCHPAD language"],"prefix":"10.1145","volume":"8","author":[{"given":"R.
