I can't currently code but about 10 years ago I was learning some programming in school and if I only remember the functions I could easily write a program like this. I can see what to do in what order and basically I see the whole program in my head. It is a simple loop. I remember I was doing something similar and it wasn't hard at all.
It would be something like:
a=1
while a=<100 do b=a/3, c=a/5,
if b=/=whole figure and c=/=whole figure print a,
if b=whole figure and c=/=whole figure print "Fizz",
if b=/=whole figure and c=whole figure print "Buzz",
if b=whole figure and c=whole figure print "FizzBuzz",
a=a+1,
repeat while.
Writing this took me like 2 mins (including thinking and remembering). I just don't remember how to check the "whole figure" thing but considering I last worked with the language 10 years ago, it was only like 3 months of 1 hour a week in my high school and I don't even know what the language was called I quess I did well anyway.
