+  Description: The pascal add-on does not work with the z16f (that is
+               configuration z16f2800100zcog/pashello).  This appears to be
+               another ZDS-II error:  when executing the instruction
+               SYSIO 0, WRITESTR a large case statement is executed.  This
+               involves a call into the ZiLOG runtime library to __uwcase().
+               __uwcase is passed a pointer to a structure containing jump
+               information.  The cause of the failure appears to be that
+               the referenced switch data is bad.
+               This is submited as ZiLOG support incident 81459.
