This mode is selected by the $MODE OBJFPC switch. On the command line, this mode is selected by
the -Mobjfpc switch.
- You must use the address operator to assign procedural variables.
- A forward declaration must be repeated exactly the same by the implementation of a
function/procedure. In particular, you cannot omit the parameters when implementing
the function or procedure, and the calling convention must be repeated as well.
- Overloading of functions is allowed.
- Nested comments are allowed.
- Inline code is allowed: There is no need to enable it with the {$INLINE} directive.
- The Objpas unit is loaded right after the system unit. One of the consequences of this
is that the type Integer is redefined as Longint.
- You can use the cvar type.
- PChars are converted to strings automatically.
- Parameters in class methods cannot have the same names as class properties.
- Strings are shortstrings by default. You can use the -Sh command line switch or the
{$H+} switch to change this.
