#2285 Help a beginner, fan.exe closes

Lokem Tue 13 May 2014

So im really new to programming in general and when i say really new i literally know nothing and the little i now is from C an imperative language, so im all confused about object oriented fantom, the reason im here is because i have to research this language as a project for one of my subjects in university.

Now i'll head to my problem, i want the fan.exe don't close inmediately after the code ends i want it to stay so i can see the output can i do this? or am i asking nonsense?

EDIT: i wanted to add that as im a beginner i would be so grateful if you treated me like a baby, im very noob im sorry.

Hi Lokem,

Welcome to Fantom.. I hope you enjoy it around here...

What you are looking for is something to stop the program from closing, usually that is:

Env.cur.in.readLine

That way it will exit when you press enter.

Or...

Run fan under a command window (type cmd into the Windows Start Menu box). Then you will see the output.

(I assume you have put the fantom executable directory in your path - otherwise replace fan by c:\fantom\bin\fan etc)

e.g.:

cd c:\fantom\examples\sys
fan lists.fan

Env.cur.readLine will work as well because it will prevent the program terminating and its window will stay on the screen till you type return.

Thanks for the fast answer, this helped a lot

Env.cur.in.readLine

Don't know why but i was in fact running from cmd the .fan when this closed window happened, thanks for the help guys again.
