DBF2ARRAY()

  Short:
  ------
  DBF2ARRAY() Returns an array of values for the current record

  Returns:
  --------
  <aValues> => an array of values in the current record

  Syntax:
  -------
  DBF2ARRAY()

  Description:
  ------------
  Returns an array of values for the current record,
  with the order of the array the same as the ordinal field
  order.

  Examples:
  ---------
   use customer

   a := DBF2ARRAY()            // store values
   for i = 1 to len(a)
     @0+i,0 get a[i]
   next

   read                        // edit them
   if AUPDATED(a)              // if they were updated from  the DBF values
     ARRAY2DBF(a)              // save them
   endif

AUPDATED()

  Short:
  ------
  AUPDATED() Determines if array contains updated values for record

  Returns:
  --------
  <lUpdated> => Are the values in the array updated

  Syntax:
  -------
  AUPDATED(aCheck)

  Description:
  ------------
  Compares the values in an array (usually created with
  a call to DBF2ARRAY() )  <aCheck> with the current values in the
  current record. The order of the array is presumed to match the
  order of the fields, and to be of length fcount(). If the values
  in the array are updated (changed), True is returned.

  Examples:
  ---------
   use customer
   a := DBF2ARRAY()            // store values
   for i = 1 to len(a)
     @0+i,0 get a[i]
   next
   read                               // edit them
   if AUPDATED(a)              // if they were updated from  the DBF values
     ARRAY2DBF(a)              // save them
   endif

ARRAY2DBF()

  Short:
  ------
  ARRAY2DBF() Replaces current record with values in an array

  Returns:
  --------
  Nil

  Syntax:
  -------
  ARRAY2DBF(aValues)

  Description:
  ------------
  Replaces the values in the current record with the
  values in <aValues>. Array order is assumed to be the same as
  the ordinal field order.

  Examples:
  ---------
   use customer
   a := DBF2ARRAY()            // store values

   for i = 1 to len(a)
     @0+i,0 get a[i]
   next
   read                        // edit them

   if AUPDATED(a)              // if they were updated from
                               // the DBF values
     ARRAY2DBF(a)              // save them
   endif
