Introduction to Pathmaker

New and Changed Information
067867 Tandem Computers Incorporated iii
The Introduction to Pathmaker manual has been completely restructured and rewritten
for this release of the product. The previous version of this manual was written for
the B41 version of the Pathmaker product; since that time, several new versions of the
product have been released. This manual describes the product based upon the
Release 3 D20 version of the Pathmaker product.
If you have already used previous versions of the Pathmaker product and want to
quickly learn about the new features and capabilities of the product for Release 3, read
the summary of new Pathmaker features in the New and Changed Information section
of the Pathmaker Programming Guide for Release 3. In addition to providing a brief
overview of the new features and capabilities, this summary includes a table that
indicates where in the Pathmaker manual set detailed information about the Release 3
enhancements can be located. This summary is written specifically for readers who
have used previous versions of the Pathmaker product and are already very familiar
with the product's basic features.
The operating system for Tandem NonStop systems, formerly called the Guardian
operating system, is now called the Tandem NonStop Kernel. This change reflects
Tandem's current and future operating system enhancements that further enable open
systems and application portability.
