Describes three popular "shareware" computer programs: PC-Write (word processing program for IBM PC and compatibles); PC-File III (electronic file system); PC-Talk III (communications program). Shareware programs are marketed at minimum profit with maximum distribution and unlimited acceptance test; are protected by copyright; and…

This third article in a five-part series focuses on personal computer software (instructional packages for the computer itself). Topics covered include 11 categories of microcomputer software, evaluation and selection, purchase, version numbers and upgrades, copy protection, disk operating system commands, preparation of master disk, batch files,…

Discusses development of an analog simulation program for microcomputers similar to those available on mainframe computers. The program is interactive, more user-friendly than batch mode mainframe simulators in use, and has user help, error detection, and medium resolution graphics for presentation of system responses. (JN)

Discusses data acquisition systems for biologists, considering: (1) input; (2) output; (3) controllers; (4) software for data acquisition; and (5) programing languages. Also discusses several biochemical databases, including those storing data on protein sequences and on chemical structures in two-dimensional form (together with biological testing…

A Heath/Zenith H/Z-90 personal workstation for a PRIME 550 host computer has been developed. The personal computer-based workstation has local editing capability with automatic upload and download of PRIME files, supports a local printer, and provides backup of files on local floppy disk. (Author)

The ability of a microcomputer to execute several programs at the same time is called "multitasking." The nature and use of one multitasking operating system Concurrent PC-DOS from Digital Research (the developers of the CP/M operating system) are discussed. (JN)

Describes a procedure for using commonly available database management systems to produce indexes on microcomputers. Production steps discussed include creation of the database, data entry, database sort, formatting, and editing. (Author/MBR)

Reviews the software package, "Interaction Analyses," which makes the observation of communication transactions--commonly described as PROANA5--possible with a microcomputer. (PD)

Description of portable microcomputers discusses design features of Tandy TRS-80, Nippon Electric Company PC-8200, Epson HX-20, Texas Instruments TI CC 40, and Convergent Technologies' Workslate and provides several caveats and recommendations to those making purchasing decisions. Potential uses for portable microcomputers in education are also…

The article summarizes a survey of major computer hardware and software manufacturers as well as of disabled (blind, deaf, and physically disabled) persons who use personal computers at home and work. The study recommended ways in which technology could be made more accessible, primarily through providing transparency and redundancy. (CL)

The article discusses uses of microcomputers by sighted, blind, and visually impaired users; strengths and weaknesses of adaptive aids; and their specific applications. The author cites the need for additional resources for training and equipping visually impaired computer users and calls for efforts to ensure equal computer access. (Author/CL)

Describes the use and advantages of a computer version of the Gunning Fog Index. Presents the program for input and use on a Radio Shack TRS-80 computer. (HTH)

Discusses the advantages and disadvantages of using dBASE for the storage and retrieval of downloaded bibliographic records, and the problems involved in importing data downloaded from various online systems into dBASE. ASCIIREF, a software program developed to allow users to easily reformat just about any file of ASCII bibliographic records into…

Describes two methods to increase the speed of printing on microcomputers: (1) buffers, which are external storage devices used to temporarily store data bound for the printer; and (2) spoolers, which are software programs used to capture printer output and send it to the computer's memory or to a disk file. (LRW)

Sixteen articles discuss the library/subscription agency relationship and changes brought about by automation in the United States. The work of the agency as publisher and in other exceptional areas is also described, and relevant activities in Great Britain, the Middle East, and Nigeria are considered. A selected bibliography on automated…
