Dipends what RDD are you using in Clipper 5
Clipper 5 uses RDD for compliant to varius DBASE dialect.
The best performance in clipper was with FOXPRO dialect using DBF - CDX - FPT
those extension aren't supported by TDBF
From TDBF Home page (
http://tdbf.sourceforge.net/) :
- Support for Clipper and Visual FoxPro specific fields.
- Index support available for fast sorting of big tables and search (NDX and MDX files). No support for Clipper and FoxPro indexes yet.
