| Abstract | The concept of macros, as a tool to extend the expressive capability of a symbolic language by techniques of string substitution, has existed in the lexicon of programming languages for many years. It has been used most effectively in connection with assemblers; in some cases capabilities not too far short of the range commonly attributed to “higher-level languages” have been provided by this means. Attempts to extend higher-level languages by similar tools have, however, not been quite as well received. In this presentation we consider the lessons which have been learned in the course of a six-year experiment with a macro preprocessor for a dialect of ALGOL 60. The factors which we find of interest are those of user convenience, flexibility, efficiency, and syntactic integrity. We attempt to relate these, in the framework of our own experience, to the independent variables of base language power, user orientation, and design goals. It is not our purpose to arrive at any sweeping generalizations; rather, we will content ourselves with drawing tentative conclusions with respect to fruitful avenues of development from a rather limited base with the help of some specific examples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
