I've been trying to get the NF from 2 arguments (not files) in awk without success .

This is the command line:

```
awk -f the_program 12/12/2013 11/11/2014

```

Is it possible to some how pipe ARGV[1] or ARGV[2] to getline to get NF?
I wanted to get NF so I can easily validate the arguments before doing other stuff with them
