[R] ARIMA0 question

Dear R People:

In library(ts), there is a function arima0
to estimate the ARMA parameters. R 1.2.3, windows

Sometimes when fitting a model, an error
occurs in the optim procedure.  This error
stops the process (which is as it should be).

When running a simulation with many iterations,
this error will stop the entire simulation.

My question is, please:
What is the best way to get out of the arima0
function when an error occurs without stopping
the whole procedure?

Thanks in advance!
