Abstract
The Rigi Editor is a practical software development environment for programming-in-the-large based on the Rigi Model. The objective of this thesis is to present Survey, a scripting language, which permits tasks performed through the Rigi Editor interface to be programmed as command scripts. To promote consistency throughout the Rigi Editor interface, the Survey programming environment is iconic, using the same hypertext editing paradigms to maintain its scripts.
UNIX programmers use the find command to perform basic file maintenance. Findtool is an application of the Rigi Editor interface as a visual interface to the NIX find command. Findtool was implemented as a prototype of Survey to investigate the suitability of the Rigi Editor interface as a visual programming environment.
In the implementation of Findtool and Survey, it was prudent to reuse as much of the previous Rigi development effort as possible. Therefore, these projects provide excellent test cases for current techniques for reusing software. A reusable system design is developed.
