Absoft Fx3™ Graphical Debugger

Fix Bugs Faster and Easier With the Best Fortran & 'C' Debugger Available

Benefits:

• Debug Fortran, C, and C++ programs generated by compilers from multiple vendors
• 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.
