It depends on how you look at it. :)

I have had plans of making a variant of POLYLINE, namely LINE, with a
starting P and an ending P
Example:
LINE [<colour>] P5 P8
gives:
2 24 X5 Y5 Z5 X6 Y6 Z6
2 24 X6 Y6 Z6 X7 Y7 Z7
2 24 X7 Y7 Z7 X8 Y8 Z8
(plus ECHOes and MIRRORs)
But yes, with a given upper limit of points, I could add POLYLINE, too.

I have thought of that, but decided not to, for two reasons:
1. It would be difficult to avoid crosslines to be doubled, since every
point currently has to be entered twice.
2. Very often, I use ECHO mode in LDS to make curved profiles go 3-D. In
those cases, the cross-lines should be of type-5. The compiler can
inpossibly distinguish between when to use type-2 and type-5 lines.
Maybe you could set a mode that generates either type-2 or type-5
cross-lines for POLYLINEs, but their rules will probably be complicated.

I like this idea. You certainly got a POINT. :)

That's not so easily coded, I think, but it should be very nice. It has
been
noted.

Thanks for the suggestions,

| (...) True. (...) Hmm. I'm not sure if that would be as useful -- there'd be all the extra lines of code to get the points into the Pn list, in the right order. That would almost offset the convenience of generating the polyline in a single command. (...) (26 years ago, 4-Dec-98, to lugnet.cad)
