Many thanks to you Akira.
Reading the file into lua tables is good sense, and thank you for the string
manipulations to pass to metafun().
From your teaching I changed t

Dear John,
How to make this a polygon?
An example:
\starttext
\startluacode
local metafun = context.metafun
metafun.start()
io.input("DATA")
local i, j
local x, y, s, t1, t2
i = 1
x={}
y={}
s="draw "

x[i], y[i] = io.read("*n", "*n")
Dear John,
How to make this a polygon?
An example:
\starttext
\startluacode
local metafun = context.metafun
metafun.start()
io.input("DATA")
local i, j
local x, y, s, t1, t2
i = 1
x={}
y={}
s="draw "
while true do
x[i], y[i] = io.read("*n", "*n")
if not x[i] then break end
metafun("filldra
I seek how to use context-lua to draw a path from ‘points’ in an external file.
Below is one way to plot points from an external file, call the file DATA with
contents:
1 3
-2 2
-3 -1
3 -2
\starttext
\startluacode
local metafun = context.metafun
metafun.start()
io.input(“DATA")
while true do
