I'm having trouble complete a record retrieval in my file. 

I know I can select multiple files by using a semi-colon between the retrieve spec parameters, such as 2102AA; 2275AB, etc.

I also know I can select multiple files by using ".." before or after a retrieve spec parameter, such as 21..

I also know I can "not select" groups files, by putting a slash in front of the parameter, such as /obs..

My question is, is there a way to "not select" multiple groups?  I'm trying to avoid selecting any file with the word "obsolete" or "000" at the beginning of an element. I've tried "/obs..;/000.. but that doesn't work.

Any suggestions?

If you want to get cars that are not green and also not red, you cannot ask for cars that are not green or not red, because all of the green cars are not red and all of the red cars are not green. You need to ask for all of the cars that are not green and are also not red.

In code:
if((color <> "red") and (color <> "green")) then ...

will get you cars that are not green and are not red.

if((color <> "red") or (color <> "green")) then ..

will get you all of the cars, because the red cars are not green and the green cars are not red.
