ft95 cexecutable is out of date

Im a new user of FTN95/Plato3 for compiling fortran source codes.Each time the program is compiled and run, it comes up with the error 'your excutable is out of date do you want ......' What is the fix to the problem?

Plato will come up with this message if one (or more) of the source code files contained within the project has been changed since the executable was last built. Plato is warning you of this and asking if you want to build before you run the program. If you build the program before running it you will not see the message.

In the Options dialog, there is an option 'On run, always build when changed'. This will supress the warning.
