openwrite
OPENWRITE filename
command. Opens the named file for writing. If the file already
existed, the old version is deleted and a new, empty file created.
OPENWRITE, but not the other OPEN variants, will accept as input
a two-element list, in which the first element must be a variable
name, and the second must be a positive integer. A character
buffer of the specified size will be created. When a SETWRITE is
done with this same list (in the sense of .EQ, not a copy, so
you must do something like
? make "buf [foo 100]
? openwrite :buf
? setwrite :buf
[...]
? close :buf
and not just
? openwrite [foo 100]
? setwrite [foo 100]
and so on), the printed characters are stored in the buffer;
when a CLOSE is done with the same list as input, the characters
from the buffer (treated as one long word, even if spaces and
newlines are included) become the value of the specified variable.
