$(nth,
which
,
arg0
[,
arg1
,…,
arg7
])
If which is 0, nth returns arg0, and so on. Note the difference between $(nth) and $(index); $(nth)returns one of a series of arguments to the function, while $(index) extracts a value from a comma-delimited string passed as a single argument. Arguments not selected by which are not evaluated.
