Vcr Plus Coder/DeCoder (text file for VCRPLUS.ARC) This programme generates (or codes) and analyses (or decodes) VCR+ codes for shows that start and end on the hour or half hour and are no more than five hours in length. VCR+ is the encrypted coding for the VCR+ module... these are the codes for the Gemstar VCR_Plus device as they appear in, say, TV Guide. If you want the coding for a show which is NOT printed, you can, of course, call their 900- phone number, or generate you own with this. Apparently a computer science/math teacher gave a college class the problem of breaking the VCR+ coding... a C-programme resulted (posted on the InterNet?) which wound up on GEnie as a ZIP file. After some trouble (most of the users could not understand why an Atari 8 bitter would want the file, for he could not run such sophisticated code), I got a listed copy of the programme. I analysed the algorithm and recoded from scratch (the coding algorithm here is much better than the original... the original algorithm, on an 8088, could take up to a minute to code... in interpretted turbo basic, mine takes a few seconds). A listed version of the programme was made available to a Commodore 64 programmer (who was intrumental in getting me a text copy of the C-programme) and has been converted to the C-64. His version was then converted to the AppleII. The programme is in TurboBasic (there are versions of Turbo that work with Sparta3.2d and on 800 systems). The archive contains a title screen (AUTORUN.BAS) along with the programme (VCRPLUS.TRB) and the full description of the algorithm (for six or fewer digit VCR+ codes... that is, those for shows starting/ending on hours or half-hours, and of no more than five hours duration). You may want to modify it to input the shows to convert from a disk file, say, instead of typing them in separately. This programme (based upon the algorithms I got from GEnie) is freeware... that is, I wrote it (so don't take credit for it and I am the copyright holder) but you are free to share this with any and all other Atari 8 bitters who show interest in it.
