I'm new to Ftn95 & Plato. Where can I find examples of the use of MODULE without leaving Plato, i.e. not having to use DOS?
Plato
If your are using a modern 64-bit version of Windows, there is no DOS in it, even if you wanted to have it. DOS was for 16-bit processors, and DOS programs do not run on current versions of Windows.
You have to come out of Plato to post in this forum, read a Fortran book that you have in one of the document formats, or use the Web. However, a standard feature of a modern operating system with a GUI layer is that you can open Fortran code (or other text) on the Web or a document file in a browser, PDF reader, etc., copy a section of code and paste into a new document in a Plato project, and then compile and run the code 'inside Plato'.
For example, try the code posted in https://forums.silverfrost.com/Forum/Topic/3624 . It is a program with one module, a subroutine and main program which both use the module.
