Runtime error

I have a marvellous Scrabble game (named "Scramble" perhaps for copyright reasons) which is a DOS program written in 1991. I copied it from an old 286 or 386 computer which someone gave me.

It is a wickedly clever game, and I am lucky if I win one time out of 20. HOWEVER it will not run on a computer with CPU greater than 33 MHz. Instead it fails to load, giving a message "Runtime error."

I would like to know what "Runtime error" means and if there is any way of getting this program to run on a faster computer.

Well I cannot say with any certainty about what Runtime Error means in general to your situation. However, as someone who writes programs this is generally generated when certain runtime libraries are not available or cannot be found and the code was not set to display a more usable message. Older programs are notorious for the "terse" error messages.

Basically, if it is a compiled program (which I suspect it is), you would need to recompile the source code with the new runtime libraries on the newer/faster machine.

I have several old programs that I loved playing and it is one of the reasons I kept an old 286/386 around. They don't work in the newer machines and I don't have the source code to recompile them.

Another thing, if you have the contact information for the game, you can contact the company/person and see if there is a newer version available. Some have websites you can go to. I have a share ware card game that I did that, the author was happy to upgrade for $5. I still have fun with the game, just on a faster machine now.

Thanks j.lupo
Undoubtedly what you say is correct. I used to play this game on a 486 DX 66 and turn off "Turbo" which dropped the CPU speed to 33 MHz.

The various computers I had which would run at 33 MHz or less have all unfortunately died -- probably from lack of use rather than age. I doubt that the original compiler would still be contactable after 15 years, and I have to load the game to find out the name (it was a "she" as I recall).

I will keep my eyes open for a slower machine that is repairable.

I had a similar problem with some old "Drill and Kill" programs that was used in my previous job. There is a program that you can buy that might suit your purposes. It is called Mo'slo.

This should allow the software to run.

Another option might be to get Virtual PC. That way you can run the program in its native os.

I hope this helps

you should be able to get it to run slow enough. Download the free trial and run it on the lowest setting.

I did experience some times that I would work intermittently. That is, it would give the error we received (Run time, Divide by Zero) message a couple of times then work.

I just took another look. Definately try the 1.5 version before buying the 4biz. I had good success with it.

To faradhi

I have visited the Mo'Slo website and it looks promising. It appears that the version: Mo?Slo 4BIZ
would be appropriate for Win 98.

Can you verify from your own experience that it could slow down a P II 400 MHz to less than 33 MHz.

PROBLEM SOLVED !!
Today I was given a Pentium 100 computer on which was installed a marvellous Scrabble game which runs in Windows (on my PII 400 MHz) with facility for up to four players -- human or computer -- and the computer players can be set on a sliding scale of difficulty from "Dumb" to "Smart." It even has sound effects.

And how much hard drive space does it use? Yep, just 331 kilobytes.

Thanks for the suggestions which I will save for further issues.
