Lahey Computer Systems and Fujitsu, Ltd. are pleased to announce Visual Analyzer (VA), a Fortran and C source code analysis tool. Graphically analyze the call structure and logic flow of your Fortran and C source code. Zero in on particular sections of the call tree and hide code that is not relevant to your analysis. Display a detailed cross reference of all the variables in the program and understand the linkage between variables in different program units. Check for argument consistency mistakes across calls, even in separate files. Understand module dependencies and where modules and commons are defined and referenced. Automatically modernize indentation for older Fortran codes. Show C variable definitions and references and check for problems in a Fortran/C interface. VA can help you understand someone else's code, detect subtle programming errors across multiple files, and verify compliance with the Fortran 95 and C standards. According to Bob Runyan, president of Lahey, "If you have a large program, whether you wrote it yourself or inherited it from someone else, and especially if the program is being developed by a team, you need VA. VA can save weeks of wasted effort. We used VA to help port a large commercial math library and would have been lost without it. We've shipped VA as part of our LF90 and LF95 PRO products since May of last year and the response has been overwhelmingly positive." "Visual Analyzer is a real winner!" says Michael Prager, Research Biologist. Visual Analyzer is $395 US and can be used with all popular Fortran language systems on Windows. System requirements: Intel Pentium or compatible processor, Windows 95, 98, or NT.
