how do i run the function?

[Rick Tan]

If i want to run a function whose name is contained in a string, how do
I do that in Ruby? or is this not feasible?

For example

def a
puts "a"
end

def b
puts "b"
end

mymethod="a"

In the above code snippet, i like to run the function a by using the
string mymethod. What trick if any can i use in ruby to make this
happen?

Thanks.

Object#send. http://ruby-doc.org/core/classes/Object.html#M000332 (It'll =
take a string as well as a symbol.)
