13. A computer program product including a tangible computer readable storage device comprising instructions stored thereon for carrying out the steps of a method for assisting a user in creating source code for a computer program in a high-level programming language when the computer program is executed on a data processing system, the method including the steps of: detecting a need for assisting the user with input for the creation of a piece of said source code at a current user inputting location within the piece of said source code; determining fitting source code elements suitable for input at said current inputting location; and providing to the user said list of fitting source code elements, wherein for each fitting source code element a respective fitting probability of the source code element in the current inputting location is determined, and wherein to each fitting source code element in the list is associated with an indication of the respective fitting probability, wherein said fitting probabilities include probabilities of software methods of a software class being invoked after other methods of the same software class.
