[fpc-pascal] read lines at end of file

Need to read the last 4 lines (txt) of a very large log file 100M bytes,
100k lines or more  lots of times - of course I can read through the file in
the normal way but this is rather slow. Is there a way to 'read lines from
the end'? I note that unix tail or its port to windows does this very fast
so guess there must be a fast way to do it in pascal too?

TIA for any ideas John
