[erlang-questions] What does Prompt in io:get_line/2 do?

[Ivan Uemlianin]

Dear All

Quick question!

In io:get_line(IoDevice, Prompt), what is the point of Prompt?  Just 
using a random atom seems to work fine.

1> {ok,F} = file:open("data.txt",[read, {encoding, utf8}]).
{ok,<0.36.0>}
2> io:get_line(F, x).
"first line\n"
3> io:get_line(F, y).
"second line\n"
% ... etc

Thanks

Ivan
