I'll try your solution in the afternoon, thanks

Quote:There's no point to checking the size of 'a' since multiple arguments in Home view would produce an argument count error (no list behavior like in CAS view) as your program only specifies one argument (which must be given in order for the program to even run).

Non-CAS programs cannot be "overloaded" to handle both cases in which an argument is passed, or when no arguments are passed. You have to specify one or the other. This is why the SIZE(a)==0 check is redundant. Just to be clear, this is regarding the behavior of a non-CAS program.

In fact, my problem was here: I would to "overload" and to handle (as I do in CAS programs) is a parameter is passed, and (if yes) whether it's only one, it's a number and so on...
Ok, if there is no solution, my controls (with your advice) will be "better than nothing"

EDIT: a trick could be give the parameter a default value, but...
