Sorry that I wasn't clear.  Using the code change that Maarten suggested, I entered:

gen double newtime = q(1996q1) + timevar-1

I got the same error code as with the earlier Generate statement.  I will study the references on Panel data.

Thanks,

Bill

What does "did not work" mean precisely? 

What did you type in Stata? What did Stata say in response?

Unfortunately, that did not work.  I should add that each quarter has 3000-7000 observations; there not one row of data per quarter.  I don't know if that makes a difference (very new at time series).

try:
 gen double newtime = q(1996q1) + timevar-1
