You're right, it's a hole in the design. However, you can approximate the latency by building some code around a forced interrupt call to see what the overhead in the kernel is for a simple task switch. Not accurate, but it will get you within an order of magnitude.

Hoo-boy. There isn't one in the public domain yet – except for G++ from the Free Software Foundation – and that is a full blown compiler that weighs in at 5 mbytes of code. Far too big to post here!
I'll see what I can do, although I'm not going to be able to unarchive anything until my new machine gets here later this week. (I'm running on floppies, due to a sick disk!)
Yes indeed. Prices are 59.95 US for overseas mail, write to Box 56188, Boulder, Colorado, 80322-6188, U.S.A for a subscription.
Even better than saying in Compuserve that the listings will be late, how about admitting it right up front–in the magazine itself in that boilerplate paragraph that you put at the end of the articles. If you had told me the listings could be expected in 2-3 months or maybe…

OK, thanks! I'll take a look!… – Troy
How could there be? There are no standard machines.
Troy, Since DDJ now sells the Small C package, I doubt that you'll find it on this forum. I seem to remember seeing it somewhere tho….maybe CPMSIG? BYTE also has a version of Small C avalable. You might want to check with BYTE Books. JIM
why not have a subtopic for "late program listings" so the questions don't get posted in the general topic? THe regulars can switch out that topic. Or better yet, include a note in the Welcome screen, so people who log in just to ask about listings will know the current…

Listings
Message #24583
I sympathize with the demands of publishing a magazine and maintaining a forum like this, and I hesitate to bring up the issue of listings again; but it occurs to me that if the listings are a full quarter behind that you could probably use some help. I am sure…
April: kabooom.c
Message #24582
I'd like to download kabooom.c mentioned in Examining Room–Cruising With TopSpeed, April 90. According to various mentions in the magazine, it may be available somewhere here, but I can't find it. Can you help? I'd like source code.
Kevin, If you read the older messages on the board, you will find that you are only the millionth person with the same question. 🙂 Briefly, the listings go from CA to NY by snail mail, and are then checked against the printed magazine and uploaded by someone for whom,…
I have used the Heap Expander on a moderately large C program which is a flat file database manager and would recommend the product to you. IN my application, I use the expanded/extended/virtual memory to hold record which are pointed to from the regular heap (ie from a linked list).…
#Where is Jeff?
Message #24579
I'd like to send a message directly to Jeff Duntemann (the Structured Programming columnist for Dr. Dobb's) does he have a CIS PPN or can you route a message to him from here? Thanks, -Stan
Picture Formats
Message #24578
Does anyone have information on the SPEG (Static Pictures Expert Group) and MPEG (Motion ….) formats? I believe these are the successors to the FAX standards already in place. Thanks.
#Apr. 90 Listings
Message #24577
I'm new in this forum, and am trying to find the listing for the April, 1990 issue, specifically the listing for the articles dealing with neural networks. Article stated that the listings were available here, but upon searching ALL of the LIBS, found nothing later than Jan. 90. Can anyone…
I have a 25MHz DTK 386 board with the 64K cache. It seems to work well with all my stuff. I only have 8Mb in it, so I don't know how it works with the full 16MB (including the daughterboard). Rahner
DICTIONARY
Message #24575
Carlos, I believe Microlytics has an OEM package available. And I know Houghton Mifflin does. As to whether you or I could afford them … Regards, …Flash P.S. If you do find out anything, could you let us know? Thanks!
Don – As the DOS wizard at work (Nobody else here has the books and tools I do so I got the pointy hat and robes ) I can steal a bit of time at work, but mainly I work on stuff like this nights or evenings. (I'm single and…
Ctree Examples
Message #24572
I have recently purchased Ctree and Rtree from Faircom. The documentation and program disks do not contain sample applications. Does anyone have any suggestions as to where on CompuServe one might find information on this? CB
Louis – My pain threshold increases at about the SQUARE of the rate of the price. And thats doublely true when it has to come from my pocket. .Jr.
#Small C Source Code
Message #24570
I'm looking for the source code for the Small C compiler, and am rather surprised that I haven't been able to locate it using IBM File Finder OR by searching individual forums. Since Small C originated with DDJ, perhaps I'll have better luck here — can someone please point me…
Relocate BIOS to RAM
Message #24569
Is the ability to relocate BIOS to fast RAM a function "built into the motherboard" or is there a utility that will do it for me? Thanks for any replys!
John, I haven't had direct experience with DTK, but I've heard good things about it. I came _CLOSE_ to getting one, from my regular supplier, when I ordered my 286 board. When it arrived, it turned out to be an ELT, which he said was a little better. Anyhow, I…
Dale – Now your Earlier statement makes more sence to me. Your not writing a sub-part for Taps but a serparte utility. More or less a frount-end to FIND or GREP. The file format your planning on using is the Offline Directory format of taps. Those I have. Right now…
When you get the ambiguous reference to a function, it usually means that you passed the wrong parameters to it. In looking at your calls to cursor, make sure you are passing the right types. If cursor(…) is not prototyped, The first call to cursor sets the types of parameters…
lint doesn't check for standards, Martin. It basically checks type compatibilities and what-not about as thoroughly as Pascal does. The big difference is that you can choose whether to ignore lint or not, where Pascal doesn't give you that choice. Joe
Martin, I believe I keep saying this (although I may be thinking of the wrong thread and/or forum), but there is no standard way of specifying data types in assembly language. Some assemblers may do this, however — it depends on the assembler. I know the two main Macintosh assemblers…

#Xlating PCX Files, AUG89
Message #24562
I would like to get hold of and tinker with Kent Quirk's PRPCX C listings. They're (apparently) only availablein the 64K AUG89.ARC – any word on unpacking this yet, or maybe just those files for his article?
#Help…
Message #24561
Hello. Please, could you tell if it's possible for an overseas user to subscribe to DDJ magazine? I live in Italy and DDJ is not easy to find… Thank you in advance. Regards, Andrea
[Continued] Actually what is presented is the measurement of the interrupt processing without an operating system present. This is the time which would be subtracted from the interrupt processing time with an operating system. The result would be the latency introduced by the operating system. Even that might not fully…
#Rhealstone Benchmark
Message #24559
Dear DDJ, I was very interested in your Rhealstone Real-Time Benchmark code in the April issue. As a result I have developed the Rhealstone code for testing DESQview using the DESQview C API. Now I am not suggesting that DESQview is a real-time system but since it implements many of…

DBase IV Programming ??
Message #24555
Does anyone know of a programming tool for parsing DBase IV memo fields? Primarily, I would be interested in doing this with the C language, but also maybe from Clipper. This raises another question. Are Clipper files the same layout as DBase IV files. For that matter, if there are…
Thanks John. -Bob

Curses
Message #24551
After performing some archeology through several magazines and catalogs, my cousin found a Lattice ad! He ordered Curses, and got your masterpiece going. It also works on my machine without any hitches, and I can use it. I haven't even read through my first issue yet, but I've already got…
Curses
Message #24550
I don't know about that very well. I suppose that's done when the header files are analyzed. The best thing is to ask an expert, not me! John Linzmeier
Mike, I'm not familiar with the "heap expander with the right price." Am currently working with an app that I've pared to 270K disk image but then once the sucker loads, Katie bar the doors… I'm using Cscape and db_file for screen and file management. There are certain places that…

The DRM is the AT&T 2.0 spec. It is well worth getting ($20 I think). I don't know the part number, but if you call AT&T you can find it. Also get the "essential readings". All that comes with C++ compilers, except for Zortech. The ARM is the "annotated reference…
Pete Becker, who wrote the Heap Exapander, now works for Borland. You can contact him directly in the Borland forum (BPROGB). I haven't looked at it since an early 2.0 release. It's a great product for what it's designed to do. And the price is right! — MF
