Ada Programming/Pragmas/Normalize Scalars
< Ada Programming | Pragmas
Summary[edit | edit source]
The pragma Normalize_Scalars directs the compiler to initialize otherwise uninitialized scalar variables with predictable values. If possible, the compiler will choose out-of-range values.
Example[edit | edit source]
pragma Normalize_Scalars;
...
My_Variable : Positive; -- Oops, forgot to initialize this variable.
-- The compiler (may) initialize this to 0
...
-- Oops, using a variable before it is initialized!
-- An exception should be raised here, since the compiler
-- initialized the value to 0 - an out-of-range value for the Positive type.
Some_Other_Variable := My_Variable;
