Screenshots of Photran

At the center of the window is our syntax-highlighting Fortran editor. The Outline view on the right summarizes the high-level constructs in the file. The Problems view allows instant navigation to sites where errors occurred.

By building on the CDT, Photran is able to provide a GUI interface to gdb.  The teal dots in the editor indicate breakpoints; the blue arrow identifies the current line while stepping through a subprogram.  The Variables view allows the programmer to browse the values of variables visible at the current execution point.
