Re: [bug-gawk] How to define a function that can accept arbitrary number of arguments?

[Aharon Robbins]

Hi.

There is no way to define an awk function that takes an arbitrary number
of arguments.  You can either define a function that take a large
number of arguments, say 10, and just call it each time with a differing
number of values and rely on awk to initialize the rest to zero, or you
can define your function to take an array parameter, which can then contain
an arbitrary number of elements.

Sorry.
