| Abstract | In this paper we examine Ada with regard to program verification and make certain suggestions towards writing potentially provable Ada programs. We attempt to isolate and discuss those features of Ada which are not susceptible to current verification techniques. From verifiability considerations, the most critical features in Ada appear to be those which deal with data sharing under concurrent processing, direct referencing of non-local variables, access variables, “approximate” data-types, and generic program units. The independence of program units along with well defined interfaces for interactions is presented as desirable not only from software engineering aspects but also from the formal proof considerations. However, the possibility of having a large number of variables, potentially sharable among concurrent processes, is likely to make the proofs of Ada programs unmanageable. It is asserted, however, that with a certain discipline on the programmer verifiable programs can be written in Ada. |

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.
