st: loop to create varialbes

Hello
I need a loop that will go through my two year panel set and create the first difference for me for each variable. I don't have a clue about these for each loops.
Here is what I tried.
foreach x of varlist _all{
generate d.`x' = 'x' - L1.`x'
the error msg I get is:
d.state invalid name
r(198);
I would like the new variables to have the same name as the old with a d in front to keep it easy to read.
Any help is appreciated.
Regards
