Jimmy,

Equivalents:
    Found() --> .not. oRs:Eof()
    RecNo() --> oRs:BookMark
    DbGoTo( n ) --> oRs:BookMark := n
    OrdKeyNo() --> oRs:AbsolutePosition
    OrdKeyGoTo( x ) --> oRs:AbsolutePosition := x
Regards,
Saludos,

oRs:BookMark --> is like RECNO() of DBF
oRs:AbsolutePosition --> is like OrdKeyNo() of DBF

After reading a recordset, both point to the same record.

After reading a recordset, we can sort the recordset in memory by
Code: Select all  Expand view
oRs:Sort := cFieldName


After sorting, oRs:BookMark points to the record number in the original order as read where as oRs:AbsolutePosition points to the relative position in the sorted order.

Usage:
Code: Select all  Expand view
uBm := oRs:BookMark
oRs:BookMark := 50.0
n := oRs:AbsolutePostion
oRs:AbolutePostion := 20
