>Is there a command in 2.6 equivalent to VFP RLOCK(0) to lock the header record. What we need is some way to lock the header to enable us to append data in a multi-user environment. In VFP, you can issue an RLOCK(0) where the parameter is the record number. If you issue this call in 2.6, it expects the work area as the parameter!

Have you tried FLOCK()?
