3e0398dbd1 OPEN NULL is a new syntax that opens a null stream.
[INTERPRETER]

* BUG: Undo one change of last revision: reading a stream from a memory 
  stream is a special case. It reads a null-terminated C string, and not a
  serialized Gambas string.
* NEW: OPEN STRING is a new instruction that allows to use a string as a 
  stream. Writing to it appends the written data to the end of the string 
  at the moment.

  new string.

  instructions alone.
