Version:           1.0.0_devel (using KDE KDE 3.3.1)

As an extension to the BIT derived type, it would be nice to be able to have a derived getdata type that would retrieve a bitfield range from another field.  So, I could extract a 3 bit number starting at bit 5 of an input field by specifying

3_BIT_NUMBER     BITFIELD input_field 5 3

or something similar to the format file.  Currently I'm implementing this through a combination of BIT and LINCOM derived fields.

Similar to C's bitfield struct.
