[R] system()

I am new to R but have used Splus for many years.  When I create many 
graphics in sequence in Splus/Linux, each time that I complete a 
page, I send a message to my command line interface using the 
following function:

FOOT <- function(PAGENO,TEXT)
         mtext(outer=T, TEXT, side=1)
         unix("cat", c(paste("Finished with page", PAGENO)),FALSE, FALSE)

In R, the corresponding function appears to be "system()".  I don't 
see how I can pass the PAGENO argument to "cat" in R.

Any advice?
