Re: How to change Dosemu files lock scheme? !!!!!quick fix!!!!!

[Kevin Noseworthy - Specialty Software <menkhor@nf.sympatico.ca>]

Setup a Novell server to hold the files
Dosemu supports Novell
I have this working with full file and record locking
using my dos database - Advanced Revelation -  i.e. Pick for DOS
Don't know a lot about xBase databases except how to suck the data out 
of them.
If clipper supports novell your off to the races.
