Erlang shell problem

Hello,

Im new to Erlang. Im using Erlang on Ubuntu 10.10. I typed erl to start the erlang shell (Eshell V5.7.4). The shell starts. But, if i type some expression in the shell like say 20+30 and hit enter im back to 1>, and the result of the expression is not shown.

What could be causing this problem ?

Please Help Thank You.

You must type : 20+30. Don't forgot DOT. Hope i can help you.... :D

Yes, it's the DOT which tells the Erlang reader that it has reached the end of the expression. There is no restriction on over how many lines an expression may stretch. This is the same as with function definitions in a module.
