RecFields( rec )
RecFields returns a list of strings corresponding to the names of the
record components of the record rec.
gap> r := rec( a := 1, b := 2 );; gap> RecFields( r ); [ "a", "b" ]
Note that you cannot use the string result in the ordinary way to access
or change a record component. You must use the
construct (see Accessing Record Elements and Record Assignment).
