[Vm-beginners] Return strings in numeric primitives

[David Leonhardt]

For more details.

With this code, I get a string and return it.

self var: #stringObj declareC: 'int stringObj'.
self var: #stringPtr declareC: 'char *stringPtr'.
self var: #stringSize declareC: 'int stringSize'.
 stringObj := objectMemory stackValue: 0.
stringSize := objectMemory stSizeOf: stringObj.
stringPtr := self cCoerce: (objectMemory arrayValueOf: stringObj) to: 'char
*'.

But I can't replace stringObj := 'Hello World'. Why?
