The hash is not expected to be unique, it just provides a starting point
for another search (usually linear ?).

Unless it's the sort of operating system that uses something like :
Sys$disk:[foo.bar.moo.lar]myfile.txt
(VaxVMS, from quite a few years ago)
And if I recall, the parsing function provided would also separate the
extension from the main part of the file's name.

The only use I now for them is when you need to plot the sine of a sine.
Or possibly to calculate the frequency spectrum of this.
Ie
x = a.sin( b.sin( y ) )
This is fundamental to Frequency Modulation.
I don't know if they apply anywhere else ?
Unhelpfully,
Richard.
