An other poster allready pointed out that you need to use access all.

But maybee you would be better off using some container library i.E. the
booch components:

http://www.pushface.org/components/bc

and since you are trying to store 

Vehicle'Class you might also want to look at the indefinte extension at:

http://adacl.sourceforge.net

Examples:

http://adacl.sourceforge.net/html
______Include__AdaCL-SAR-Filter-Container__ads.htm

http://adacl.sourceforge.net/html/sarDo-CommandLine__adb.htm#176_15

The interesting Part: You won't need any access any more. 

With Regards

Martin
