I don't understand.  If you have 10 records of differing structure, you
clearly will need to have 10 different compare procedures.  Is this not
the situation?  It's really the compare's that need to be different.  10
instantiations of a generic sort routine is hardly a significant cost. 
You can make the records the same (for purposes of the compare and sort)
by having a record which contains a key (big enough for any data) and a
pointer to the actual data, or an index into an array or file.  Is that
what you want to do?
