"Hello World" in Visual Prolog
|
|
|
| Hi,
I've downloaded Visual Prolog 6.2. Could someone tell me how to make a
simple "Hello World"-program.
Thanks,
P

| Hi Petri, I expect that you mean a non-GUI program that writes to "standard
output". You should create a "console" project. And then modify the "run"
predicate like this:
run() :-
stdio::write("Hello world\n").

| Thank you, but how do I create a non-GUI program? Can't find such option?

Perhaps I was a bit "short". A non-GUI program is called a "console"
program. Anyway, here is more elaborate description:
Start Visual Prolog and select "Project -> New...".
- Type in a "Project Name" (here I assume "myProject")
- Select UI Strategy = console
- And choose a base directory for your Visual Prolog projects.
Press "Create" and then build your project (Alt-F9). In the project tree you
can see all the files which are in your project. A lot of the files are
"library" files, containing library code, like access to the console.
Your main file is called "myProject.pro" (assuming the project name
"myProject"). If you doubl click it, it will open in an editor.
And then you can change the code as I wrote before.
Finally, you can run the program F9 (or for console programs Shift-F9 is
usually better, becaue that will keep the console window open after your
program terminates.
You can also press F6 to run your program in the debugger (not much to debug
in a hello world program, though).
regards Phil
