Zlatin,

>I know how to workaround, but if I wish to use descriptive parameters names it is not possible. 16 parameters each with lenght of 16 characters is not a common scenario, but it may happen, as in my case.

I'd recommend that you check out the Wiki article http://fox.wikis.com/wc.dll?Wiki~OperandPrinciple . I am a firm believer that object properties should be used instead of having methods that require tons of parameters.
