Well, I wasn't going to go into the details but...a user of my FROG
database browser reported the problem.  With FROG the user can open any
database file and browse the records in the file.  One file in particular
has 796 columns!  So a "select * from myfile" returns every column in 
the file.  I adivsed the user to limit the number of columns returned but
it's much easier to type a "select *" than "select fld1, fld2, fld3, etc..."

It's pretty unusual to have files with that many columns but it does 
happen!
