==Ordinary Programming==

In case you skipped the introduction, this is a last reminder that the fireworks start with Distributed Computing, and you can [[Walnut/Distributed_Programming|go there now]], or continue to read about normal, ordinary computing in <span class="e">''E''</span>, starting with Hello World.

But first, we need to declare what version of E we're using here.

-
-	To run an <span class="e">''E''</span> program, put "println("Hello World")" into a text file. Make sure the file extension is ".e" (to run Swing-based apps, use extension ".e-awt", and to use SWT-based apps, use ".e-swt"). Type

-	~~into a command shell (a DOS window under Windows, or a Cygwin or Unix shell, such as bash). The greeting will be printed to your display.~~
-
-	Now that you have started rune and run Hello World, it would be a good time to look at your trace log folder for the first time to make sure you know where to look. If you are on Windows95, the trace log will default to c:\windows\temp\etrace. The etrace folder location can always be found in the eprops.txt file in the <span class="e">''E''</span> installation directory (under Unix, you will have created eprops.txt yourself from eprops-template.txt). You should, after launching rune, find one file in the trace folder, which is the trace log created for the rune session. It will probably be empty, unless you have gone wild experimenting with Hello World.
