Since you are not being very specific I will be very general and refer you to the FM and have you look up the LAG function!

Dear Listserv,
my database is setup as follows:
ID Visit BMI
1 1 23
1 2 22
1 3 30
1 4 23
1 5 23
etc
I would like to keep the database in the same format and compute percent
change in BMI.
I only know how to manage this if the database is transposed. Rather than
transposing the database
and then restructuring it again, is there a way to do this?
Many thanks in advance,
Leah
