Thank you for your help. Do you have any advice on where I could read up about macros?

At 07:00 PM 4/1/2004 -0500, you wrote:

i is a local macro (and must be referreed to as `i' when used in
expressions) , not a variable and you want j to be the same (after all, they
have nothing to do with observations, they are just counters).

local j=`i'-1

It would be worthwhile to read up about macros if you want to program
effectively or write complicated loops.
