- fileversion
- Version of file multiplied by 10, e.g. 70. 
- tablename
- Name of table as stored in the file. If the database was created
       by pxlib, then this will be the name of the file without the
       extension. 
- numrecords
- Number of records in this table. 
- numfields
- Number of fields in this table. 
- headersize
- Number of bytes used for the header. This is usually 0x800. 
- recordsize
- Number of bytes used for each record. This is the sum of all
       field sizes (available since version 1.4.2). 
- maxtablesize
- 
      This value multiplied by 0x400 is the size of a data block in bytes.
      The maximum number of records in a datablock is the integer part of
      (maxtablesize * 0x400 - 8) / recordsize.
      
- numdatablocks
- 
      The number of data blocks in the file. Each data block contains a
      certain number of records which depends on the record size and the data
      block size (maxtablesize). Data blocks may not necessarily be
      completely filled.
      
- numindexfields
- 
      Number of fields used for the primary index. The fields do always start
      with field number 1.
     
- codepage
- 
      The DOS codepage which was used for encoding fields with character data.
      If the target encoding is not set with
      px_set_targetencoding() this will be the encoding for
      character fields when records are being accessed with
      px_get_record() or
      px_retrieve_record().
