Y2K Compliancy

December 15, 1998

Valued R.R. Software customer:

We are often asked about the year 2000 (Y2K) compatibility of our products. We agree that the year 2000 (Y2K) problem is a significant one for many businesses. Fortunately, Ada 83 and Ada 95 were designed with a date type with a range that includes the entire 21st century. The Ada validation suite has been testing year 2000 issues since 1984. This makes it unlikely that any problems with Y2K calculations exist in any of our products.

All of our compiler products, and almost all of our tools are written in Ada 83 or Ada 95. Time and date calculations are very rare in these products, and all of the products use the standard Ada date type.

Of course, our products depend on the host and target operating systems for some time and date operations. We cannot prevent Y2K problems which are caused by a host or target operating system.

We have instituted expanded Y2K testing of the current version (3.1.1d) of our Ada 95 compiler products. Additional tests exercising the Calendar package were constructed, and the compiler and tools have been tested on computers with dates set to various dates just before and just after January 1, 2000. No problems were detected.

We do not anticipate formal testing of any of our other compiler products, including all of the Ada 83 products. Since the technology in these products is very similar to the Ada 95 products (since the Ada 95 were built as enhanced versions of the Ada 83 products), we would not expect any problems to be found there.

Our Claw product line does not use any date or time operations other than those provided by the Ada compiler in use. Assuming the Ada 95 compiler do not have any Y2K problems, Claw will not have any, either.

In the unlikely event that a Y2K problem is found in the current version of any of our products, R.R. Software pledges to fix them for free. (This does not include problems caused by the use of a faulty operating system or Ada 95 compiler other than Janus/Ada).

Sincerely,
