[fpc-pascal]Temporary file names under GO32

[Aitor Santamaria Merino]

Has anyone ever written a function to get a temporary unique file name?
DOS has a function:
Int $21, AH=$5A

but as I am not acquantied with the FILE records, and where the handle 
is stored, I was wondering if someone has ever done this.

Otherwise, I suppose I can always make a function based on current 
date/time...
