Fx3™ is the industry's most complete debugging and excellent for C/C++ and assembly language as well. Fx3's easy-to-use graphical and command line interfaces and extensive feature set, provides superior analysis and control during the debug process on x86_64/Linux, Windows and Mac OS/Intel systems. Debug multi-threaded OpenMP Fortran programs. Compatible with compilers from Absoft, GNU, Intel and Pathscale means Fx3 is very cost effective because a single copy can work with compilers from multiple vendors. Designed by Fortran experts for Fortran. The only commercial Fortran debugger designed by Fortran experts, Fx3 is much more effective than gdb and related debuggers because Fx3 handles Fortran constructs that gdb and other debuggers do not understand. Fx3™ can handle it all efficiently in a user friendly environment. The Absoft Fx3™ Graphical Debugger is the successor to the popular Fx2 Debugger and comes bundled with all Absoft Pro Fortran products for Windows, Linux and Mac OS at no additional cost. Fx3 is also available as a stand-alone product for x86_x64 Linux systems and MacOS/Intel. Key Benefits & Features of Fx3 Include :
Key Benefits
Benefits:- Complete graphical and command line interfaces
- Debug Fortran, C, C++ and assembly language programs generated by compilers from different vendors
- OpenMP - Fx3 displays multi-threaded OpenMP Fortran sessions
- Identify problem areas in programs quickly
- Detect, diagnose and repair bugs more easily
- Verify logic without time-consuming output constructions
- Stop and restart programs dynamically
- Change variable values interactively
- Debug Fortran, C/C++ and assembler code all from the same tool
Easy to Use:
Fx3™ allows you to focus quickly on identifying problem areas in programs. The Fx3™ Debugger comes with a graphical user interface (GUI) with point and click ease of use. This GUI is complete with tabbed source code and assembly views, toolbars, and dock-able stack, console, symbol, register windows, source browser and memory windows. Dynamically updating windows and visual indicators help developers readily see the changing state of a program. Automatic source code "tool tips" and color syntax also make it easy to obtain the current state of programs at a glance. Setting breakpoints and controlling program execution is also a snap. The "save" feature allows developers to easily save and restore information about a program's debug session, such as breakpoints, source paths, program arguments, console and symbol window history, active symbol window variables, and the working directory. The symbols window is easily navigated with either a mouse or keyboard accelerators. The graphical user interface can be customized for each individual's work flow. Source browser allows easy navigation of program source files and functions. Advanced Fx3™ users can enter any command line debugger commands via the console window, or configure the debugger interface to their individual taste via the preference dialog, and dock-able windows and toolbars. Fx3™ tracks the current state of your program and provides dynamic feedback by automatically tracking and updating the current stack frame, instruction pointer, local, static, and global variables, the current register state and program status. View windows can be docked, floating or closed allowing the debugger to be configured for a developer's typical workflow.
