                      The Data Base Management System

It is a very simple minded system.  A data base is a file.  The file has  a
header  with  a  magic number and the current number of entries.  Follows a
fixed length sequential table of records.  Each record is  the  transform's
identity and a pointer in bytes to its location in the file.  When adding a
transform, the system first tries  to  fill  the  holes  left  by  possibly
removed  transforms.  If  none if found, the size of the file is increased.
Compacting is done separately.

The data base editor can dump the content of  a  file,  selectively  change
transforms, remove them, or create new ones.  The active transform on which
modifications are made, can be renamed stored and read which allows for all
possible combinations.
