I've only had the PDL for a brief period so far --- not enough to
thoroughly evaluate its usefulness, but it does seem to be a fairly
interesting package.  It would have been nice if the "Getting Started"
pamphlet contained a bit more information on the overall design and
use of the system, but the on-line help is thorough.
  
There is an error in the FLAGS section of the online help (which is 
also present in at least Edition 1 of the Programmer's Reference
Guide flag table):  After flag -22 there is a statement that math
exception indicator flags are set whether an event is treated as an
exception or an error.  This is not true.  The appropriate flag
(-23 thru -26) is set only when an event is treated as an exception,
as controlled by flags -20 thru -22.
  
The math exception/error handling is a valuable concept which, among
others, is not addressed in the HP48 manuals.
