Vidyasagar#x2014;A Bengali-Ahamia Text Processing Attachment

摘要

#x201c;Vidyasagar#x201d;, a text processing system comprising of a text entry terminal with VDU, a dot-matrix printer and software is described. The hardware attachment can be connected to any suitable host through serial links to form a word processor, file creation unit or a file enquiry unit for Bengali/Ahamia text. The coding scheme (BIIC) and the QWERTY style keyboard employ simple consonants, vowels, operators and are accommodated in 7-bit, 96 character ASCII space. Host resident high-level languages can process BIIC files as if they are 96 character ASCII files, permitting standard file processing routines to be used. Additional host resident software are used to edit BIIC files, convert them to justified, paragraphed and paginated printable files with composite consonants, display the file in VDU or print them in the dot-matrix printer either with complex conjunct consonants or in analysed mode (without consonant conjuncts). The coding scheme has built-in facilities to accommodate most other North Indian languages.
