directly the bdl do not know, but save the file.mi with version 19 and version 17 opens it quietly while for the pgk you have to use the command that is in the zipped folder; Just that when you are in version 19 "Down" that file.rec and you will find yourself in the temp folder of c: your save17.pgk file where there is everything you have at root.
Since you also made the switch from 17 to 19, I asked you if you knew a procedure to use the lisp that worked in version 17 also for version 19.
