newbie MOMENT question [message #6567]

Hi,

I want to compute the mean and variance of a set of data points, and
I'm using the MOMENT procedure to do it. With some fields, the
variance is quite small (i.e., o(e-03)), so I get floating point
underflow errors when MOMENT tries to compute the skewness and
kurtosis. since i don't really care about the skewness and kurtosis,
how can i get IDL to not worry about this, and continue with the
rest of the procedure? online help suggests that some combination
of ON_ERROR and/or CATCH would appropriate, but i haven't been
able to figure out exactly how to use these two yet. any suggestions?

thanks,
charlotte
