LINC Development Assistant

LINC Development Assistant

LINC Development Assistant (internally LINC Design Assistant) was originally developed by Roger Jaquin using Smalltalk/V from Digitalk running on DOS. Because Smalltalk/V contained its own GUI, this enabled a graphical interface to show relationships between LINC modules.

LDA was then moved to Smalltalk/V 286 to take advantage of the extended memory addressing of the DOS extender.

In 1989, David Anderson took over as team lead and spearheaded the move to running on OS/2. This allowed OS integration of look and feel and a reduction of the Smalltalk base code. Some functionality was moved to C/C++ (using an early C++ compiler Zortech).

By the end of 1990, Windows 3.0 was proving to be very successful and LDA was ported to Windows using .

LDA had some very innovate elements including a graph that did an automatic layout of elements. The LINC model would be loaded into LDA and using the graph layout and other tools, the model could be analysed and modified.
