If you use (or can use) a batch file to start whatever program you want to run, there used to be small utilities that would do this. The ones I use are CAPSON.COM and CAPSOFF.COM. You should be able to find them in an archive some place, or you can send me a note and I can send you a copy.

Sorry about the duplicate (and old) posting, my browser hiccuped and reposted this.

Not to hijack this thread, but could someone explain why mounting the C:\ drive is not recommended? I have some programs that I run in XP's "DOS" on my C: drive, and I'd like to be able to run them in DOSBox as well without having to re-write various batch & configuration files. Thanks!

The original problem with the text getting truncated is fixed by the "Dynamic" switch. I suspect the gaps in the lines and the text issue were the same. The characters in this program are drawn, rather than being pulled from a font file. They can be scaled somewhat arbitrarily. Thanks for the …

So, what would be the likely difference between Ykhwong's build and the CVS/0.63 builds? Differences in actual sourcecode, or compiler differences? I'm assuming sourcecode, in which case, how does one track it down?

I'm trying to use DOSBox to rescue some old engineering software. By using the Windows CVS build, most things seem to work pretty well. One thing I've discovered is that there are some quirks that appear when I try to plot anything. The system uses VGA graphics, and long straight lines have …

Many thanks to both Dominus and to wd! I downloaded the CVS Dominus compiled and it works like a champ! wd nailed it. You guys rock! Now I can get to back testing & hunting for more bugs...

I'll check out ykhwong's archives. I realize that the primary thrust is to support old games, but I'd be surprised if there isn't one or two out there that would run afoul of this as well. I don't know if there is a downside to using a switch. I suppose the compiled code will be more compact if it's …

Thanks! That was quick. I'll have to look into an older CVS build, or getting set up to compile the source myself. The last time I worked with a compiler was about 20 years ago, so I'm a bit rusty. In the meantime, I'd like to suggest that a config file switchbe installed for this in future releases …

OK, here's a test program that will re-create the problem at will: http://users.rcn.com/gwhite/APL/DBOXTEST.zip It works fine if run directly in XP, both on a Dell system and an IBM laptop, but it produces only integer results in DOSBox. I also discovered today that a previous version of the APL …

Because the application is actually a programming environment, I can create a small executable that will demonstrate the problem. I'll rig it up to run a sample set of calculations with a copy of the correct answers on-screen I'll park it on my website and post a link to it on Monday. Thanks!

Well, I downloaded the latest CVS compile, and it works better in many ways, but it's still returning integers for all calculations. I'm at a bit of a loss for what to do next, but I will be happy to work with anyone who understands the inner workings to try to chase this down. In the meantime, I'm …

Thanks! I'll try CVS-Compile/AEP-EMU version. Unfortunately, the web site appears to be down at the moment. There is a huge amount of valuable work that was done in DOS for scientific & engineering problems. I even know one guy who still sells a specialized CAD package that only runs in DOS. I know …

I have a huge amount of enginering software written in a DOS version of the APL language that I need to keep running. Microsoft's support for DOS is increasingly pathetic, so I figured DOSBox might save my bacon. There seems to be a bit of a problem with math operations. All the computations I've …
