Contents return instruction

With a return instruction like e.g.. return a function is left. Within a function thereby optionally a result can be returned. The function is terminated thereby.


Example: we define a function for doubling values, which will return a result with the return instruction.
 
Function name double
Function parameter x
Instruction for return return 2*x

function verdopple(x):
  return 2*x
In another place of the program the call of this function with the instruction y
= verdopple(2)

leads to the assignment of the result 4 to the variable y.
