See the help page ?backslash:

- The backslash is ignored if it occurs within numbers. Therefore, when
  entering long numbers, the backslash can be used to separate groups of
  digits for improved readability.

Alas, this does not apply for 2D input.  There is a someone cryptic aside to that effect in the help page:

- Note: The examples on this page should be viewed in 1-D.

The format is explained in ?debugopts.  It is [DEBUGSTACK, (group-of-3)₁, (group-of-3)₂, ..., (group-of-3)_n],
with (group-of-3)_i = (name-of-procedure, current-statement-in-procedure, list-of-arguments-to-procedure).

Wish I'd thought of it---with luck I'll remember that one.

I understood that.  My comment was in reference to the blanket statement that the mode=log option does not work with any plot-driver from command-line.  It works with the maplet plot driver, but that requires user interaction.  Hmm.  Maybe that can be modified ...

Using axis[2]=[mode=log] will work from command-line maple if you use plotsetup(maplet), as acer mentioned.

I'm guessing the imaginary values come from the arcsin.  Try using the 2 parameter arctan block (Inverse Tangent 2) to extract the angle.  Could you use a revolute joint and extract the angle directly?  Or does that constrain your system?

Use ?convert/permlist to convert to list notation:

convert([[1,2,3], 'permlist', 3); # The 3 is the degree of the permutation
                                                [2, 3, 1]

Does the model work when you bypass the precision subsystem? How are you sensing the angle?  You could upload the model here, or contact Maple support directly.

You might consider making that operation a subsystem with precision as a parameter.  It then is easy to compare the effects of different precisions.
