i have a question, it seems like that i cant use n_ in the do loop, and have to change to be n_{i}, is there any tricky for it?

also, what would be the final data set look like? as following?

test1 ............ test 1000 n_1 ..................n_1000 n1_1......................n1_1000...................


and each one has 2000 obs?

thanks a lot

so in that case, all the first 1999 obs are not valid but only the last line is needed? because, I guess for n_, the 2000 obs should be valuing from 1, 2, 3, until 2000?

do u have any idea how could i add those p1_, p2_, p3_ as the last three observations under each variables (instead of being added as 3 new variables....)

thanks a lot!

BTW, I HAVE ANOTHER QUESTION, BY USING: "ARRAY TEST{1000}" IN THE DATA B STEP, WE DONT NEED TO USE: ARRAY TEST{1000} TEST1--TEST1000 FOR LOADING THE ARRAY?

one more silly question......should it work? i tried (but probably with some problem?), and it seems that the portion will be replacing the last obs instead of appending after the last one....
