Raul, Thanks for the feedback. It sounds like you are doing the right things. I cannot check j803 just now because I cannot launch it on my Mac. So I use j801. I think the version of tgsjhs you downloaded is up to date.
I am sorry for the problems. Please try entering the following in the field where fd 20 is offered (after clicking the Restart button). goto ,: 20 20 30 [if you prefer, prefix the command with (dyadic) 0 or 1 to move only one turtle.] This should move BOTH turtles to a new spot on the canvas and in the ijx window you will see something like the following after click enter therein. yw 149.036 74.0546 0 ┌───────┬─────────┐ │Heading│0 149 0│ │ │0 74 0│ │ │0 0 _90│ └───────┴─────────┘ pt 45.8186 22.3957 0 ┌───────┬─────────┐ │Heading│0 149 46│ │ │0 74 22│ │ │0 0 _90│ └───────┴─────────┘ fd 41.833 78.7401 0 ┌────────┬────────┐ │Position│20 20 30│ │ │20 20 30│ │ │ 0 0 6│ └────────┴────────┘ pt _45.8186 _22.3957 0 ┌───────┬─────────┐ │Heading│0 149 0│ │ │0 74 0│ │ │0 0 _90│ └───────┴─────────┘ yw _149.036 _74.0546 0 ┌───────┬───────┐ │Heading│0 0 0│ │ │0 0 0│ │ │0 0 _90│ └───────┴───────┘ On Thu, Dec 4, 2014 at 2:35 AM, Raul Miller <[email protected]> wrote: > This sounds promising. > > That said, I tried the above steps (adding: as preparation steps, > downloading > http://www.jsoftware.com/jwiki/BrianSchott/code/turtleGraphics/tgsjhs?action=AttachFile&do=get&target=tgsjhszip.png > as tgsjhszip.zip, creating a directory at j64-803-user/projects/tgsjhs > and unzipping it there, and saving the code you presented as > j64-803-user/catmullclark.ijs ... > > However, nothing displays for me from the updated dp command.
