<br>
I have two beginners question.<br>
<br>
1) I start learning by the tryerlang site. And I did succeed in the list part. But the last question is to display the HEAD and TAIL. How do I do that.<br>

Alternatively, you can use the built-in functions hd/1 and tl/1, e.g. if I have a list in the variable List, hd(List) gives the head and tl(List) gives the tail.</div>

2) I like to use Sublimetext as a IDE. But how do I make a programm then run.<br>
<br></blockquote><div><br></div><div>When you have compiled, either manually via erlc or with a build tool, run "erl" and call the function in the module you want to run. Nothing IDE-specific there, sorry.</div>
