It is difficult, however, to invent suitable names if we have many variables.  The names may become not-suitable if the program is changed, which causes misunderstanding.  Besides, concrete values are often more helpful than variable names when we try to understand a program. From the observation above, we propose a programming language that does not use variable names.  Source code is written with concrete values.  Given multiple concrete values, executable code is generated by the technique of `programming by examples'.  In this manner, the source code can be considered as an explanation of execution.  Though there is a scalability problem, it is possible that a part of a program is written with concrete values while remaining part is written with ordinal variable names.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"74","bibliographic_titles":[{"bibliographic_title":"第55回プログラミング･シンポジウム予稿集"}],"bibliographicPageStart":"69","bibliographicIssueDates":{"bibliographicIssueDate":"2014-01-10","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2014"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:54:40.375983+00:00","id":113013,"links":{}}
