FTN95 Help System Overview

Silverfrost FTN95: Fortran for Windows is a 32 and 64-bit Fortran compiler for computers using the Microsoft Windows® operating system. It is comprised of several parts including: a Fortran 95 compiler, linker, debugger, Integrated Development Environment (IDE), documentation, ClearWin+, a run-time library and assorted tools.

Fortran compiler

The Fortran compiler is the heart of FTN95. It takes Fortran source files and turns them into something that a PC can run.


The linker, slink, takes the output from the compiler and combines with the run-time library to produce an executable. The linker quite often does its work silently and is hidden by tools like Plato.


Sdbg is the debugger you would usually use to debug FTN95 compiled programs.


Plato is an Integrated Development Environment (IDE) which will allows you to set up projects, edit source files, compile, link and debug your FTN95 programs.


ClearWin+ is a library of functions and subroutines that enables Fortran developers to produce Microsoft Windows® applications very quickly.

Run-time library

The run-time library is a collection of subroutines and functions that you can use in your programs.

.NET Support

In addition to regular Windows applications FTN95 can also compile Fortran for Microsoft .NET.
