# How to: make 0+ variable-arity argument; put text between args

What's problem you are encountering?

How do I allow for an empty list result?
Can I put some text between the 1 and 2 ?

No
.............

Yes
.............

Could you demonstrate how to?

Clarification: How do I make the block initially show up with zero placeholders instead of one?

Might be possible via xml hacking

There's no way to do that (even with xml hacking)

Wait, what are they talking about?

Sorry, I can't think right now

Ok. Thanks, all.

Like the "with inputs" of CALL, RUN and LAUNCH (oh and TELL and ASK) but the text being between inputs. (IIRC @bh wants this, too)

There are two different features under discussion here, and yes, I want both of them.

1. The ability to control the number of input slots shown in the palette for a variadic input. Specifically, I want to be able to specify the minimum, default, and maximum number of slots, so for example 0/0/1 would make an input that's optional rather than truly variadic, 1/1/∞ if at least one value is required, etc.

2. The ability to make input groups, including as a special case the ability to label an input with an associated title text.

Jens isn't exactly against either of these; he just doesn't think they're as important as I do.

Good with both. Thanks!
