The Silverfrost FTN95 default installation includes a number of programs that illustrate the use of
ClearWin+. These are installed to a folder of the form
\Users\xxx\Documents\FTN95 Examples\clearwin. Particular attention should be given to the demonstration programs
that illustrate the use of the ClearWin+ function winio@ and to the 'Browse'
application that is typically found in \Program Files (x86)\Silverfrost\FTN95.
The following instructions explain how to compile, link and execute a very
simple Windows application without using winio@.
Consider a program to calculate the squares of a sequence of numbers and print
In Fortran this takes the form:
PRINT *,idx,' Squared is ', idx*idx
Using your editor, type in the above program and save it as (say) test.for.
Open a DOS box and enter a command line of the form:
FTN95 TEST /LINK
This will produce an executable file called test.exe that can be run from
the Program Manager in the normal way or by entering:
at the DOS box command line.
The above procedure will run your test program and display a window that
presents the output. This program illustrates how ClearWin+ can be used to
convert a simple DOS application without the need to attend to any Windows
programming features. It automatically generates what is called a ClearWin
window that handles the input and output in a Windows environment.
Further information about compiling and linking is given in
Compiling and linking whilst ClearWin
windows gives detailed information about using ClearWin windows. A
major part of this guide deals with what are called format windows
using winio@. Format windows provide a quick and easy method for
developing fully featured Windows applications.
