The functions starts to parse with the CurToken() of io_rText.

the following Context.
This function returns, when a context has parsed some characterss
and completed a token OR left the context.

NOT cut from io_rText.
If the function has found a valid and complete token, PassNewToken()
passes the parsed token to the internally known receiver and
