Think about it a bit. Function 1 requires you to build up a string
piece by piece. Can you work out how to decide how many 1000s, 100s,
10s, units and so on the number contains? Then you would just need to
work out how to join the characters together. 

Similarly the 2nd function - work out what each character means in
terms of numerical value and then add them together. It's not as hard
as it seems.

Cheers,

Chris
p.s. there are some helpful functions in the back of the Ada Language
Reference Manual (findable on the web if you don't have it).
