OK. There are 3 issues here:

1)  "null" is a keyword. It is used for "null" statements, and as a default
value for access objects. You can't create a variable with that name any more
than you can create a variable named "if".

2) The value you are looking for is "ASCII.NUL", not "ASCII.NULL". (A quick
check of the package specification would have told you this.

3) The package ASCII is obsolescent, so I wouldn't use it in new code if I were
you. You should be using "Ada.Characters.Latin_1.Nul".
