| Abstract | We have designed and implemented an algorithm which measures APL-programs in the sense of software science by M.H. Halstead /1/. The reader is assumed to be familiar with the theories of software science. Our purpose has been to find the best possible algorithm to automatically analyse large quantities of APL-programs. We have also used our measuring tool to make some experiments to find out if APL-programs and workspaces obey the laws of software science or not. Becasue our purpose was to analyse large quantities, i.e. hundreds of programs we have not implemented an algorithm, which gives exactly correct results from software science point of view, because this would necessitate manual clues to the analysing algorithm and thus an interactive mode of analysis. Instead of it we have strived for a tool, which carries out the analysis automatically and as correctly as possible. In the next section some difficulties encountered in the design of the measuring algorithm and some inherent limitations of it are discussed. Section 3 summarises the sources of errors in the analysis carried out by our algorithm, while section 4 gives a more detailed description of the way analysis is carried out. The remaining sections of this paper report on some experiments we have carried out using our measuring tool. The purpose of these experiments has been to evaluate the explaining power of Halstead's theory in connection of APL-programs. However, no attempt has been made to process the results of the experiments statistically. The results of the experiments have been treated here only when 'obvious' (in)compatibilities between the theory and the results have been observed. Possible reasons for the (in)compatibilities are also pointed out. |

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.
