Visual programming languages.

Abstract

Visual programming languages enable physicians and other computer users with little knowledge of programming to develop computer software. The physician uses a visual paradigm to "draw" the computer interface and then attaches short segments of computer code to buttons, menus, and list boxes. The programs can be written for DOS or Windows and can be used with various printers and input devices (a keyboard, mouse, or pen). This article describes the development of an example of a medical program, which calculates the treadmill score.
