Ralf's Int List didn't give any details on file naming strategy
using by the temp file generator.

It looks like it's always a 8 character filename with
no extension and I'd like to use it but have to make sure that's it indeed
always has 8 characters exactly.

Thanks.

; temp.asm Create a temporary file with a unique name,
; it must be deleted manually
