I try to use close, but look at the while condition, this set PortFile to none,
because the find after last ocurrence, then the close not work properly.
If, after the while, I open again the same file, this operation have not error,
and the port can be used normally.
The question is: what happen with PortFile under the surface?.
[
SomeThing: "x10"
PortFile: open/read %file
qty: 0
while [PortFile: find/tail PortFile SomeThing][
qty: qty + 1
]
]
