I am quite sure that {color;width;style} glines points
would be more accurate as {color;width,style} glines points
since the pen specification is list of two boxes.

glines
display line connecting points
{color;width;style} glines points
Of course the whole thing is flaky since it's a mixture of j notation
with {} having a non-j meaning.
