Hello All,

I am familiar with the LAG function. It allows you to use a value of a variable from the previous observation in hte calculation of a value of a variable for the current observation.

What I need to to is if there is a function which allows you to take a value of a variable in the NEXT observation and use it in operations on the current observation. If so, what is it?

For example, I want to take the value of the variable UNIT in from the observation that follows my current one and assign it to a new variable in the current observation.

something like:

if unit='.' then unit1=next(unit);

I don't think "next" is what i want, but what is?

Thanks,

Randall
