Hi Craig

>The user still doesn't need to login. Capture the workstation name and store it in a table. That's can be invisible to the user.

I have tried something like the following but have a problem is that at times the 2nd-3rd user is allowed to FCREATE() the file already assigned to the prev user ie. 1st-2nd resp. How to avoid allowing to use the same filename. I have tried it on the same machine seperate DOS boxes.

Please advise.

        *** seed and ignore the first returned value
        m.zfilename = intrandrange(00000000, 99999999, 87654321)


        FOR m.zusercount = 1 TO m._vsomaxuser
                *** get an integer for use as a filename
                m.zfilename = ALLTRIM(STR(intrandrange(00000000, 99999999))) + ".acu"
                m.zfh       = FCREATE(m.zfilename)
wait window "1" + str(m.zusercount) + " " + m.zfilename + str(m.zfh)

                IF m.zfh > -1
                        *** Person is no longer using the application and did not
                        *** log out properly, now that we have the open handle keep it
                        *** open and exit
                        EXIT
                ENDIF
        ENDFOR


wait window "2" + str(m.zusercount) + " " + m.zfilename + str(m.zfh)
        IF (!m.nomore) AND (m._vsolan AND m.zusercount > m._vsomaxuser AND m._vsomaxusers > 0)
