nth

Evaluates and returns the argument selected by which.

$(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.

Examples

$(nth,3,eni,meni,mini,mo)	mo
$(nth,3,$(+,100,0),$(+,100,1),$(+,100,2),$(+,100,3))	103
