Or rather 

***********
forv i = 2002/2008{
***********

to avoid confusion with the variable "year".

BTW, -keep-ing and -preserve-ing/-restore-ing is not the best way to achieve
your goal. Just condition your "commands" with the -if- qualifier. 

Also, I cannot see where you actually -append- any data...

Look at the -foreach- syntax diagram, or read up on it in NJC`s
http://www.stata-journal.com/sjpdf.html?articlenum=pr0005. Even better:
-forvalues-

***********
forv year = 2002/2008{
di `year'
}
***********

Hello,

I am working with panel data and I need to separate the data by year,
run some commands, and then append it.  The BY command will not work
with this particular command so that is not an option.  I have tried
the following commands and it keeps telling me invalid syntax.  Does
anyone see an error here or have a suggestion(s)?

Thanks,
Matt

use "G:\Merged_Joined_Appended
files\final_oshpd_oscar_merge_w_dp_first_set_variables"
sort year
cd g:\Years
preserve
  foreach i of year 2002/2008 {
          keep if year == `i'
          * run my commands here *
          save year_`i'
          restore, preserve
  }
