in order to speed up the system for all, there is a sharable ddt
available. the operating procedure is almost the same as for
old ddt, namely:


@ linkr (file) -sd file.obj

to run your file without ddt:
@ run (program) file.out
to run with ddt (shareable):
@ run (program) ddt file.out

notes: the linkr program will run much faster! however, the
file.out, though runnable without ddt, is still very
large (about 25 blocks)- it leaves room for ddt.

since the shareable version uses 8k (system requirement) and the
actual ddt only 6k, both will remain for people with large
programs.
