Re: Advanced file manipulation (multiple question)

Hello!

Thanks for your helpful advices, and sorry for 1/my english,
2/abscence of details and 3/my error about Lady Lovelace name, Ada
(and not ADA or anything else). I Hope this next post would be better
:)

So, first, my OS: Windows 2000 Pro. I use Gnat 3.15 (public).
I started Ada as a student, with few advices and then... concurrent
programming the next week (semaphore etc...), that was rather... hard,
for beginners!
So, my excuse if I don't know how call OS functions... maybe you have
links where I can find tutorials about this ?

This answer seems easier for me, and I'll add a "compare-file"
procedure... I'm a bit paranoid :)

Thanks a lot for your help
