Martin,
It uses system clock.
sys(2015) returns 10 char value guaranteed to be unique on a given computer even if called in the same millisecond.
sys(3) is another one returning 8 digits 'almost' unique filename.
Use sys(2015) to create temp files.
If you need absolutely 8 in lenght, thinking a temp file's lifecyle is not long, you could use :

'_'+substr(sys(2015),4)

or make 2 chars part of extension :

stuff(sys(2015),9,0,'.')
