I don't the exact answer to your problem but may be able to point you in the right direction. PROLOG.SYS --> the purpose of this file is to store the TURBO environment in which you are working, i.e window sizes and positions on the screen, the Stack size, ect. This is setup via one of the menu options (sorry can't rember which one). PROLOG.OVL --> this file is used when generating executable code, and must be in the same directory as all the other PROLOG.* files. So what I'm saying is these two files serve totally different purposes. I may be able to offer some other advice if required so don't hesitate to contact me.

This is the second such request to occur on this net in a couple of days and it worries me. Newsgroups such as this should avoid giving advice about ripped off software. Now I am certainly not the one to "cast the first stone"! What you do is your business. But newsgroups shouldn't become like the more grubby bulletin boards. Anyway, AIAI should be able to afford the peanuts that Turbo costs! Chris Moss

Firing from the hip is dangerous, Chris, especially when it involves quoting out of context. The message you quoted from continues: > Is the problem that our version of Turbo is out of date (the manual is > copyright 1986)?

I see nothing there to suggest that the system was "ripped off", in fact the phrase "buy the whole system again" implies that it was legitimately purchased (which it was). Perhaps if we are to avoid becoming like "the more grubby bulletin boards" Chris Moss should read articles with a little more care before making irresponsible accusations. -- Tim

I apologize Tim and John. I misread the line >> However, the application's README file says it requires a file called >> PROLOG.OVL from the Prolog diskette. as being the Turbo README file, which would imply the Turbo disk was incomplete. I withdraw the comment utterly. It strikes me that it's the application that's probably out of date. MS-DOS hasn't used .OVL files for years has it?

MS-DOS >hasn't used .OVL files for years has it? TURBO-Prolog version 2.0 (the current version) uses a file PROLOG.OVL. The original TURBO-Prolog manual does not mention this file. I don't know at what stage the .OVL file was introduced. This file is distinct from the PROLOG.SYS file which stores setup information such as window sizes and default directories. If your TURBO-Prolog system works and doesn't have a PROLOG.OVL file, then a PROLOG.OVL file is not needed. Having said that, the problem could be that the application in question may use features not provided in TURBO-Prolog version 1. I should have thought that the best thing to do is just to try running the application. If it doesn't work then it needs a later version of TURBO-Prolog. I don't know what Borland offer in the way of upgrades, but if it proves impossible to get a free or cheap upgrade, I believe there is a scheme run by Borland by which educational users can get a significant discount. Ask Borland for details. I hope this information is of use. Andrew.
