I can create user functions thru Given-Find block:
But I cannot do it with Minimize function 
Is it possible? Have you some examples?
Thanks!

This time its a true catanary by definition, so we don't need a proof 😉
As for your problem: I already had written it in my first answer here - the function argument (L in your case) must be also an argument of the function you wish to minimize (PE in your sheet). Even though PE does not need L and L is a dummy argument for PE.
BTW, in case you hadn't noticed. There is no need to zip or rar Mathcad sheets anymore - they can be attached directly (as it should be).

Yes, it IS possible. The variable x must also be an argument of the function you try to minimize - even if x is just a dummy argument there.
BTW, in both examples above we could use the minimize function standalone as we don't provide any constraints. You could delete the keyword "given" and the function would still work.
Post your worksheet so we can see what you are trying to achieve.
Here is a very simple example:
You may also provide the guess value as function argument
