Hi,
I get sometimes the wrong directionpoint. In the example below it
works for all values of direx except between 0 and 90. If I put direx
to something in this interval, it seems that the point between cs and
cl are chosen.
Is there a better way to construct the paths not to get this problem?
Thank you very much Garulfo!

Does enabling entities help?

I have strings I get from an XML that I want to turn into labels for objects in
a METAPOST picture (using MetaFun). These strings can have arbitrary characters
