st: running product

["Hugh Gross" <hughgross@attbi.com>]

Is there an easy way in Stata to create a running product similar to the
ease with which one can create a running sum using the sum command?

In the example below, variable "a" would be the existing data and variable
"b" would be the desired result.

Data:

a    b
1    .
2    2
3    6
4    24

Many thanks.
