1. A method performed in a data processing system by a subprogram written in a first programming language, the method comprising:

  • receiving a parameter in a form suitable for the first programming language;

    converting the parameter to a form suitable for a second programming language that is different from the first programming language, where the form suitable for the second programming language prevents a compiler from generating code to gather the parameter when the subprogram is compiled by the compiler; and

    invoking another subprogram written in the second programming language and passing the parameter in the form suitable for the second programming language.
