Manages library (book lending &amp\; returning etc.) records in a password-protected way. Has an adder to add up to 40 later-modifiable numbers each even multiplied by a factor (say, 1 or 2). Granthaalok is meant for managing in a password-proteced secured way the book-lending &amp\; book-returning information of a small library, such as someone's personal (books &amp\; discs) collection, a neighborhood library or the mini-library in an academic department. (It doesn't take care of the financial aspects of the library at all.) It simply revolves around the nine basic processes of entry of new books, admission of new members, book-list viewing, member-list viewing, book-lending, book-returning, book-search, book-disposal and member-farewell. There are nine prominent bi-lingual command-buttons for these nine basic processes in the central working screen, and to this familiar screen the program conveniently keeps returning. Performing these processes are extremely user-friendly tasks in Granthaalok. In addition, it has an in-built number-adder (say, to add prices etc.) that may add up to 40 (later-modifiable) numbers, each even multiplied by a factor such as 2 or 3 etc. (by default, 1).
