Function

A function is declared as follows:

def add(a, b): 

  return a+b

end

The function can then be called like this:

result = add(1, 4)

It is also possible to give function arguments default values:

def add(a=0,b=0):

  return a+b

end

If default values are given in the declaration, arguments can be either input or skipped as below:

result = add(0,0) 

result = add()

When calling a function, it is important to comply with the declared order of the ar- guments. If the order is different from its definition, the function does not work as ex- pected.

Arguments can only be passed by value (including arrays). This means that any modi- fication done to the content of the argument within the scope of the function will not be reflected outside that scope.

def myProg()

  a = [50,100]

  fun(a)

  def fun(p1): 

     p1[0] = 25

     assert(p1[0] == 25)

     ...

  end

  assert(a[0] == 50)

  ...

end

URScript also supports named parameters.
