range in parameter

range in parameter

[Dennis Haney]

I have a program which has a switch takes a number between 0 and 100:

_arguments  \
        {'(-v)--volume','(--volume)-v'}"[Set audio volume to N 
(0-100)]:volume:" \

But how do I specify that all number between 0 and 100 are valid params 
without having to type all 100?

Like this:

_arguments  \
    {'(-v)--volume','(--volume)-v'}"[...]:volume:({0..100})"
                                                 ^^^^^^^^^^

That's not using any special _arguments magic, by the way.  The {0..100}
form is expanded anywhere regular brace expansion applies.
