STL contains a broad set of algorithms that perform the most common kind of data manipulations programmers use, including searching, sorting, merging, copying, and transforming. The algorithms work with data types residing in different data structures. For example, the find algorithm in STL works on lists, vectors, files, or data structures for which the concept of finding makes sense.

STL also formally defines iterator, the standard data-accessing concept. STL defines several categories of iterators, each providing a different way of accessing data. A forward iterator guides the algorithm through the data from beginning to end. A bi-directional iterator lets the algorithm move forward and backward. A random-access iterator can jump around. All the algorithms are written in terms of these abstract categories. Because of this, one implementation of an algorithm works with any type of data structure.

The implementation of STL may be obtained by anonymous ftp from butler.hpl.hp.com in the directory/stl. For more information contact Hewlett-Packard Company, 3000 Hanover St., Palo Alto, CA 94304.

C/S ELEMENTS++ combines the capabilities in C/S ELEMENTS with C++ support. Features of C/S ELEMENTS++ include a separate C++ API that incorporates its own C++ libraries, as well as third-party libraries. In addition, C/S ELEMENTS++ automatically generates both C++ application code and class definitions. Additional C/S ELEMENTS++ features include the following: virtual functions that support advanced, object-oriented programming techniques such as customization by subclassing, representation of both GUI and non-GUI objects as C++ classes, and support for C++ in the Data Access Element via the C++ API.

C/S ELEMENTS++ supports Microsoft Windows, Sun Solaris, SunOS, and HP9000/HP-UX systems. C/S ELEMENTS++ is priced at $6,850 for a developer and deployment license. There are no run-time fees. For more information contact Neuron Data, Palo Alto, CA; (415) 321-4488.

QA C v4.0 includes support for analyzing C code that contains embedded SQL statements. With QA C v4.0, users will be able to parse C code with embedded SQL statements prefixed by EXEC SQL or $ and identify syntax errors, non-portable SQL, and invalid or questionable coding practices. QA C can access relational databases including those from Sybase, Ingres, Oracle, and Informix.

QA C supports UNIX platforms including those from SUN, HP, DEC, and IBM. QA C is also available on 386/486/Pentium PCs running SCO UNIX. A QA C v4.0 license starts at $6,000.

With MacAnalyst and MacDesigner v4.3, object-oriented designers can draw diagrams using Booch, OMT, Coad/Yourdon, or Shlaer/Mellor notations with dictionary-defined class attributes and operations. Information for attributes and operations include data types and function argument lists. Source code consisting of C++ or Object Pascal interface files and function code frames can be generated.

Features of the tool suite for database designers include entity-relation diagrams (ERDs), customizable Details dialog, Data Dictionary, and foreign keys. Also ANSI-standard SQL can be generated to create the database for a relational database system (RDBMs). Designers using structured analysis and design methods can add function-return data types and function argument lists to each model and automatically generate function code frames in either C, Pascal, Basic, or FORTRAN.

Other features of the MacAnalyst and MacDesigner Tool Suite v4.3 include customization options and a project menu. Code can be generated for a set of design diagrams or added incrementally to existing code files for selected diagram objects.

UPData stores the information in a compressed data file, which can be returned by a user to the developer for analysis. Based on that data, developers can focus their efforts on the areas where they can provide the most benefit. For example, defaults and options can be set to streamline the interface and make it smoother and more intuitive to use; coded optimization can be made to frequently-used routines; and areas where documentation, training, or online hints would help most can be identified. When UPData is used to track internal code warnings and errors, a problem discovered by a user will automatically generate an accurate log of the condition that led up to the error.

UPData is priced at $79.95 and contains both the Windows and DOS versions. For more information contact Cimulus Automation Systems, Inc., 2901 Hubbard Rd., Ann Arbor, MI 48105; (313) 769-4108.

Additionally, High C/C++ reports the number of times a bad division result could occur without Pentium-safe floating-point division code. Developers can also analyze increases to execution time that result when using a software solution. According to David Wilcox, manager of technical support at MetaWare, "The software solution will be made available to customers with current versions of High C/C++ for extended DOS, Windows, and OS/2. New versions of High C/C++ for extended DOS, Windows, and OS/2 will include the Pentium fix."

With the VBI Kit, developers can create and integrate specialized visual editors into the Galaxy Visual Resource Builder, letting the developer work with custom and specialpurpose objects without leaving the Galaxy visual environment. The VBI Kit also lets developers modify standard Galaxy editors to operate on extended Galaxy objects within the Visual Resource Builders or replace galaxy visual editors with editors tailored to corporate objects, or modify the function of standard Galaxy visual editors to ensure that objects are used consistently across development groups.

Galaxy supports UNIX, Macintosh, Microsoft Windows, Windows NT, OS/2, and OpenVMS platforms. The Visual Builder Integration Kit is priced at $4,995. For more information contact Visix Software Inc., 11440 Commerce Park Dr., Reston, VA 22091; (800) 832-8668 or (703) 758-8230; FAX: (703) 758-0233.
