If I'm not mistaken, your code should work with Ada 95, but not with Ada
83, which doesn't allow universal integer EXPRESSIONS in ranges when the
type isn't explicitly stated.  For the same reason, in Ada 83 you can't
write for I in -1 .. 1 loop, because -1 is an expression.

Is the compiler you mentioned Ada 83?  If so, you can fix the code either
by writing
Some_Limit : constant Integer := 1024;
or by writing
for I in Integer range 1 .. (Some_Limit - 2) loop
or by writing both.  I  hope this helps.
