No, I'm not that smart. 8-)
I always considered that type of entry a missed key operation and tried to filter it out.
Here is my feeble attempt at that http://www.theswamp.org/forum/index.php?topic=5494.msg68365#msg68365

........    What happens if the user enters an invalid point like
8 <enter>

I'vecome back to this ...
8 <enter> could be considered valid because of
the AutoCAD direct distance entry mechanism.

ie : return a point 8 units in the direction of the cursor

You were trying to trick me Alan, yes ?

Kerry,

As you problably already know if you are going to allow for the 'Dynamic Distance Entry Method' then you are going to have to test for AutoCAD version info.  Which adds even more to your prog.

just my 2c.
