This tutorial shows you how to develop a simple Windows application using a
Silverfrost Fortran compiler and ClearWin+. It takes you through a step-by-step
process leading to an interactive program that produces the factors of a
user-supplied integer. This "Number Factoriser" is one of the demonstration
programs that is supplied with ClearWin+. The full source code can be found in
the file called factor.for.
The tutorial is based on a number of files called factor1.for, factor2.for,
etc. that can be found in the ClearWin+ demonstration directory installed on
your hard disk. These files present stages in the development of the full
program. The files are listed in the tutorial together with a detailed
line-by-line explanation of the purpose and effect of the code. The idea is
that you should compile, link and run factor1.for and then read the
explanation for this file. Then proceed to factor2.for and so on.
