Type Parameter
Syntax {$NODEFINE identifier}
The NODEFINE directive
prevents the specified symbol from being included in the header file generated
for C++Builder, while allowing some information to be output to the OBJ file.
When you use NODEFINE, it is your responsibility to define any necessary
types with HPPEMIT. For example:
type
Temperature = type double;
{$NODEFINE Temperature}
{$HPPEMIT 'typedef double Temperature'}
