[WildCard65]

Originally Posted by Emp` The attached version now packs a length cell, removing the length cap from before. DSTRING_BUFFERLEN is now only used with VFormat. (ie. Format and AddEx functions) Per WildCard65, length is a property and no longer uses the buffer. Also, added double inclusion block and changed function name cases. Furthermore, DString inherits the DataPack methodmap, demonstrating dual methodmap usage.

Emp, your include has a compile error with the property, it expects a new line after naming the property, but it got a '{'
Edit: Another thing, your methodmap is also useless, in it's current position it's referencing no function so it f***s the compiler.
After moving the methodmap to under all the functions it references, it has more compile errors.
Errors after moving methodmap:

PHP Code:

Done

Above errors caused by doing: new DString() which is replaced with: DString_Create
