Introduction to G2++

The remainder of this tutorial is about extensions to the G2 scheme. We begin in the section, ``G2++ Programming Language Interface'', by describing the programming language interface to G2++. The section, ``Support for iostream(C++)'', shows how records can be read from and written to a variety of sources and sinks simply by using different kinds of streams with the I/O routines. The sections, ``Support for String(C++)'' and ``Support for Vblock(C++)'' discusses two library components that are used in the G2++ programming language interface ( String(C++) and Vblock(C++)) and sections ``Support for Vblock(C++)'', ``Arbitrary Size Strings and Arrays'', ``The Initial Capacity of Strings and Arrays'', and ``Pathological Record Definitions'' show how to take advantage of the arbitrary sizes these types afford. In the section, ``Using G2++ with User-Defined Types'', in this topic, shows how to define G2++ records containing user-defined types and how to build the infrastructure necessary to get the I/O routines to work properly with these. Manual pages for G2++ are provided. (See g2++comp(CP), G2++(C++), G2++(4C++).)
