Hi Maarten

sorry I have to ask again about the loops:
What would be my lname and do I use in or of list? I have like 30 variables that have to be scaled by at. 
If I use of what would be the name of my varlist or can I just set a random name for that?

Concerning the macros, I would do it with ds [varlist], I guess the name from above and then say var/at?

Thanks a lot for your help
