SCO mail system

[Lance Ellinghouse]

Does anyone know how the people at SCO lock their mail files
when they are scanned in by mail? I would like to write a similar
one that does not have the shell escape and I cannot figure out
what they use as a lock. DO they actually lock it, or do they use
a temp file?

Thanks,
Lance Ellinghouse
