Developing a Hypercard-UNIX Interface for Electric Mail Transfer.

摘要

The Hypercard-UNIX electronic mail system (HUES) was programmed using Hypercard version 1.2.5 on a Macintosh computer system. HUES was created as a user-friendly way for U.S. Army Human Engineering Laboratory (HEL) employees to transfer electronic mail, as well as files of various types and formats, to anyone connected to the Internet. (Note: The Internet is a collection of many networks that service universities, private industry, and the Department of Defense.) The system is essentially an interface or shell, which receives information from another computer system (in this case, a UNIX system) and displays the information in a format that allows easier user interaction with the UNIX system. The system receives information from another computer by using a group of transmission control protocol/Internet protocol (TCP/IP) code resources developed by Apple Computer, Inc., for use with Hypercard and Macintosh computer systems. This transfer of information allows users to take advantage of the Macintosh's point-and-click user interface to perform desired procedures, instead of having to type UNIX commands. The system was designed to be expandable, with two different means of establishing a connection to a host computer (i.e., modem or TCP/IP). The system also allows direct manipulation of UNIX files, (i.e., deleting, viewing) and the option of directly sending UNIX commands.
