each Field in Object #!F-adobe-times-bold-r-normal--18* o #!EF , the routine returns
the Object specified by #!F-adobe-times-bold-r-normal--18* name #!EF (typically an Array). Object
#!F-adobe-times-bold-r-normal--18* o #!EF can be a simple Field or any Object
that can contain Fields (e.g., Groups or Series). #!N #!N If
Object #!F-adobe-times-bold-r-normal--18* o #!EF is a single Field, a single Object
is returned (typically an Array). If Object #!F-adobe-times-bold-r-normal--18* o #!EF is
anything else, the Object hierarchy is preserved, and each Field is
replaced by component #!F-adobe-times-bold-r-normal--18* name #!EF . #!N #!N Return Value
