How to add description to a function parameter?

My question is short:How to add description to a function parameter in LotusScript?

An example: I decide to use a function in one of my LotusScript Libraries, and I include it by the USE sentence. Then when I type my function I should be able to see a short description of each parameter in my function I decide to use:

I have a function inside a library called ReplaceSubString. When I type:

a=ReplaceSubstring(x, “OldText”, “NewText”) I wish this to appear on the screen:

a=ReplaceSubString(, , )

Thank you for your help!
