CONTENTS OF VOLUME #27 1. It is always a real pleasure to pass on an upgraded program. Ironfingers Penley had bought a hard copy of a government public domain program of LISP written in Pascal. He converted it to Pascal/Z but pooped out before he got all the bugs out. He donated the program on Zug volume #14. Then Lanfranco Emiliani of the Netherlands took and de-bugged it, added some bells and whistles and donated it back to us. I think he has done a good job and for those of you who are interested in artificial intellegence, this is a good starting point. LISP.COM/PAS/DOC INITLISP INITLISP.STB 2. Rex Buddenberg has come through for us again. This time he took on the public-key crypto subject. It is not complete, but he has started on it and for anybody who can help push out the frontiers they are certainly most welcome. As a relief, he has included a simplistic program on large formating. It is different in that there is provisions for a 80 column and a 132 column size printer. PRIME.COM/PAS/DOC/TXT (this the crypto stuff) PRIME1.PAS SIGNS.DOC/PAS/TXT SIGNS11.COM SUBMISSN.ABS SIGNS6.COM FONT.DAT A note from Rex with the submission states: PRIME.. prime.pas prime.com prime1.pas (random.pas from the library) (unit1.pas/pz from the library) PRIME was an attempt to implement the RSA data encryption algorithm found in Byte, Jan 83, p 198, by John Smith. Not everything works, so I didn't submit it all but some lessons may help others. See PRIME.DOC for more detail. SIGNS Files: signs.pas font.dat signs6.com signs11.com The signs programs are an update of the earlier version in VOL 19. Output may now be routed to screen, printer or a file. The program also looks more like real Pascal rather than warmed over BASIC now. The two .com files are for 6 and 11 letters respectively. 3. CLAY CARLEY III of Spokane, Wash has written a combination useful utility and a CPM function tutorial. His program will erase a file in a user friendly way and uses functions calls to do a lot of its work, which is educational for you CPM'ers. ERASE.COM/PAS 4. Greg Acland wrote some interesting comments to this library file so for those who are interested in random numbers better check this out. RNDKNUTH.LIB 5. The teachers in Sacramento, Ca were using this program for their students but I never had time to see if it would run, as is, but I didn+'t want this to go to waste. So I am including it for anyone who would like to do it as a project. There is a copyright release by the authors. BIOSIN.PAS 6. Ray Penley, bless his iron-fingers, has upgraded his student programs. Read TUTOR.PRN to get some excellent pointers and instructions on programing. STUDENTS.COM/PAS TUTOR.PRN
