Hi, am I correct in assuming that the variables arg0, arg1, and so on can only appear in expressions? In other words, this is ok: x <- arg0 + 2 but this is not ok: arg0 <- 2 function process arg1 # do something Thank you

is it okay to not allow defining identifier names of the form "arg<number>" at all?

Yes. Otherwise, there would be no way to differentiate between a normal variable and a command line argument.
