"un"def Types

(1/2) > >>

paule32:
Hello,

is it possible to "un"def given Types ?
I would try to compile a system.pas unit, and the fpc compiler tells me,
that SmallInt is dupplicated.

Here is the line:
type Smallint = -32768..32767;

How can I "un"def SmallInt, if exists, and when yes, then re-type it.

Thanks for reading

PascalDragon:
You can't because SmallInt is an internal type provided by the compiler itself.

Thaddy:
What is your purpose?

Leledumbo:
Not for system unit. Elsewhere, you can override it while still referring to the system unit one by fully qualified name. The compiler has internal type definitions (about 8 or so) that cannot be changed without changing the compiler (system unit alone is not enough).

circular:
You could redefine the type so that it cannot be used.
