[REBOL] A bug in file port? Re:(2)
From: rebol:techscribe at: 18-Sep-2000 16:55
Hi Geo,
then I recommend you skip to Chapter 21 (page 673). It's all about ports.
(Specifially page 677 bottom says:
We can return fp to the head of file with the head function:
fp: head fp
}
In case you haven't discovered it yet, I'll think you'll find the detailed
review of the open function (pp. 678) quite enlightening. It reviews the
port object that is returned by the open function in some detail.
