FWIW, you can use SECONDS() instead of SYS(2015) to create unique file names:

LOCAL m.lcFileName, m.lcTempDBF, m.lcTempCDX
m.lcFileName = 'XX' + STR(100000 + SECONDS(), 6)
m.lcTempDBF = m.lcFileName + '.DBF'
m.lcTempCDX = m.lcFileName + '.CDX'

<--- Add your code to create the temporary table and index. Then, when you are finished, do this to clean up:

USE IN (m.lcTempDBF)
DELETE FILE m.lcTempDBF
DELETE FILE m.lcTempCDX

I have used this approach in quite a few network apps (many concurrent users) with no problems at all. If you have a concern about two users running this code at exactly the same instant (theoretically getting the same value for SECONDS()), then you could substitute 'XX' with something like the user's login code or workstation ID in order to guarantee uniqueness.
