I added a new class in my project to put general utility routines from APL+Win.   Below is the text from the class definition.   The function VTM runs fine in Cielo Explorer.  All the {}s are balanced.  I cannot make the build error "unexpected token <endblock>" go away.   The error line number is the last line of the code, where the closing  } is located.    I wonder if some combination of characters in the converted APL+Win code makes VisualApl think there is an open block?

George,

This is fixed now in the RC2.4

It was a problem with the way we dealt with the comments between the class and the namespace closing braces. 

Glad you found this one!
