#24602 TEXT SEARCH Message #24613
From: Al Stevens DDJ Forum · Forum Business March 28, 1990 3:34 PM
Brad, You can back away from the Curses stuff by backing off one month. The project was completed when I decided to use the Lattice library to add some displays. All the indexing and search code is in the months that come before the Curses column. I never compiled with…
#24599 DOS CALL TRACING? Message #24612
From: Al Stevens DDJ Forum · Telecommunications March 28, 1990 3:34 PM
Chris, TopSpeed C has a TSR named WATCH that does what you are looking for. Al Stevens
#24516 C++ types Message #24524
From: Al Stevens DDJ Forum · Forum Business March 21, 1990 11:36 AM
The point I'm making is that you have to teach what works if the student is going to write code that has to run. If what the manual says differs with how the compiler works, you have to teach the compiler. What choice do you have? The code has to…
#24423 curses Message #24428
From: Al Stevens DDJ Forum · Forum Business March 12, 1990 9:57 AM
The curses library comes with the Lattice C compiler. Lattice sells the source code to the library for $125.00. Al Stevens
#24410 C++ types Message #24415
From: Al Stevens DDJ Forum · Forum Business March 10, 1990 8:52 AM
No, my book is not Zortech specific. It is a C programmer's C++ tutorial and is about C++ 2.0, and avoids anything "tricky" if I can help it. It has many compilable exercises, some of which do not work with Zortech 2.0, particularly the chapter on iostreams. I asked a…
#24408 #C++ types Message #24414
From: Al Stevens DDJ Forum · Forum Business March 10, 1990 8:25 AM
Agreed, when viewed from the perspective of the compiler developer/purveyor such as yourself, the RM should be the guiding light. But from the perspective of the working programmer or the teacher of programmers, the way things work should prevail. You've got to use what's out there. Bjarne is a commanding…
#24403 #C++ types Message #24407
From: Al Stevens DDJ Forum · Forum Business March 8, 1990 12:03 PM
In the absence of a standard, there are no bugs, only implementations. The bugs are in the eyes of the creator, not the user. What the user sees is how it works. Even with a moving target, you must teach beginners about the real world. Ivory tower stuff might be…
#24388 Interupt.h, Extend.. Message #24400
From: Al Stevens DDJ Forum · Forum Business March 7, 1990 11:56 AM
Cristian, Here it it: /* ———– interupt.h ———— */ /* ——- the interrupt function registers ——– */ typedef struct { int bp,di,si,ds,es,dx,cx,bx,ax,ip,cs,fl; } IREGS; #define VIDEO 0x10 #define DOS 0x21 #define KYBRD 9 #define KEYBOARD 0x16 #define TIMER 8 #define KBDATA 0x60 #define KBCONTROL 0x61 #define KBSTATUS 0x64 #define ZEROFLAG…
#24382 #C++ types Message #24399
From: Al Stevens DDJ Forum · Forum Business March 7, 1990 11:49 AM
John, The difference between "what does cfront do" and "what is right" is moot when you are teaching. Why teach what the RM says if the software doesn't work that way? New C++ programmers want to know what to expect when they code and run programs, not what some AT&T…
#24368 C++ types Message #24378
From: Al Stevens DDJ Forum · Forum Business March 6, 1990 9:36 AM
For the last time, John, I HAVE THE REFERENCE MANUAL. (Read my caps.) It was free. The author gave it to me. Please stop answering every question with "get the reference manual." It sounds patronizing. Besides, my question was not about what is in the manual. I can read the…
#24374 Al's C++ window.c Message #24377
From: Al Stevens DDJ Forum · Forum Business March 6, 1990 9:36 AM
Chances are the code from that issue doesn't work with Zortech 2.0. I developed it with 1.7 back when I was first exploring C++, so it might not be (probably isn't) 100% C++. Al Stevens
#C++ types Message #24364
From: Al Stevens DDJ Forum · Forum Business March 5, 1990 11:52 AM
Greg, I notice that the Zortech compiler treats enums as distinct data types while another 2.0 compiler does not. The other treats them as int equivalents. With Zortech you can overload an operator by specifying different enum types just as you can with classes. With the other one you cannot…
#24317 DICTIONARY Message #24350
From: Al Stevens DDJ Forum · General/DDJ office March 4, 1990 9:09 AM
You can get a library of words from Austin Code Works. They are not hyphenated if I remember correctly. You'd need to write your own search programs. The indexing logic in the C column TEXTSRCH program could be helpful for that.
#24096 C++ Question Message #24101
From: Al Stevens DDJ Forum · General/DDJ office February 17, 1990 9:29 AM
Amend that estimate to the "average C++ experience." Not many new programmers will start out on C++.
#24075- #C++ Question Message #24077
From: Al Stevens DDJ Forum · General/DDJ office February 16, 1990 9:34 AM
That problem, figuring what the classes should be, is the classic one confronted by programmers who are moving to the object-oriented paradigm. I've only seen one book on OOPS that used real examples. To conform to the paradigm, which is defined from a Smalltalk point of view, most OOPS programmers…
#23732 #Windows and Novell Message #23738
From: Al Stevens DDJ Forum · General/DDJ office January 24, 1990 3:12 PM
John(s) If I understand what you are recommending, you are trying to get a small loader that would execute application .EXE programs in a Novell network. The idea is to keep the users from getting at the licensed copies of the real thing; the users would have no privileges to…
From: Al Stevens DDJ Forum · Forum Business January 24, 1990 3:11 PM
Joel, I have an evaluation copy of CLEAR+ for C from: CLEAR Software, Inc. 637 Washington St. Suite 105 Brookline, MA 02146 (617)232-4720 It makes some pretty neat flow charts from C programs. Al Stevens
From: Al Stevens DDJ Forum · Forum Business January 21, 1990 6:00 PM
Dean, I made no comparisons such as you suggest. Al Stevens
#23678 #ZTC v2 and old cols Message #23680
From: Al Stevens DDJ Forum · Forum Business January 19, 1990 1:12 AM
EricF, Sorry, I do not have the new Zortech. Al Stevens
From: Al Stevens DDJ Forum · Forum Business January 19, 1990 12:48 AM
Dean, I just used TopSpeed to build a small system. I nover once needed to go to the user's manual to figure out how to use the environment's editor/compiler. The performance seems to be on a par with TC. There are a lot of features I haven't tried yet. It…

Hypertext.
#23556 #Key Compression Message #23573
From: Al Stevens DDJ Forum · Forum Business January 9, 1990 2:45 PM
June is a special issue, and Jon gave us an unusually early deadline for that one. I'm working on April now. Al Stevens
#23555 #C++ for the masses Message #23572
From: Al Stevens DDJ Forum · Forum Business January 9, 1990 2:45 PM
I am not aware of any official announcements from BI, JPI, or MS. There are a lot of rumors though. Rumors rarely contain reliable delvery dates. That's why I'd advise anyone who wanted in now to get something that's shipping now. They can switch later if they want. I have…
#23543 Key Compression Message #23544
From: Al Stevens DDJ Forum · Forum Business January 7, 1990 3:44 PM
shmuel, Amend that last thought to read, "a node navigator must be serial." Obviously a b-tree navigator is not serial. Dumb me. Al
#23530 #Key Compression Message #23543
From: Al Stevens DDJ Forum · Forum Business January 7, 1990 3:39 PM
Shmuel, I've done it, and I talk about it in the upcoming June 1990 issue, but I didn't include any source code. Here's how I do it. Keys in a b-tree node are in collated sequence. The first key in a node is always whole, that is it contains all…
#23529 #Help Message #23542
From: Al Stevens DDJ Forum · Forum Business January 7, 1990 3:38 PM
Kevin, Try "C Programmer's Guide to NetBIOS," W. David Schwaderer, 1988, Howard W. Sams & Company. It includes a lot of C code that compiles with Microsoft C 5.0. Al Stevens
#23532 #C++ for the masses Message #23541
From: Al Stevens DDJ Forum · Forum Business January 7, 1990 3:38 PM
Bob, If you want to get into C++ now and a PC is your only avenue, you should get either Guidelines or Zortech. Neither MS nor BI have made any announcements, so a delivery date would be mere speculation at this time. You'll need the MSC compiler to go along…
#23524 #C++ for the masses Message #23527
From: Al Stevens DDJ Forum · Forum Business January 6, 1990 4:29 PM
Helmut, There was no substantial source code with that article, so there is nothing in the libraries about it. The article appeared in the DDJ Bonus Issue C Sourcebook for the 1990s, which hit the streets in December. It's still on newstands, and subscribers got it bundled with the January…
#23522 #Help Message #23523
From: Al Stevens DDJ Forum · Forum Business January 6, 1990 12:52 PM
David, If you want to stick with QuickC, try Kent Porter's "Stretching QuickC." He has another book called "Stretching Turbo C." Both cover the same material but with the features of the particular compiler. Both are published by Brady Books and are in the stores now. Kent's graphics stuff is…
#23503 #C++ for the masses Message #23515
From: Al Stevens DDJ Forum · Forum Business January 5, 1990 8:44 PM
Bob, I have used Zortech C++ and Guidelines C++. Al Stevens

Thanks, Matthew; now if someone could do that for *me* with OS/2… Al Stevens
#22962- #OOP Message #22999
From: Al Stevens DDJ Forum · Amiga at Work November 27, 1989 6:44 PM
I do not completely agree. We won't see an infinity of such articles although we will see a few. There is still an audience for them. Seeing an unfamiliar language used to build an old chestnut of a data structure helps many young programmers to learn the language because they…
#22888 #OOP Message #22900
From: Al Stevens DDJ Forum · General/DDJ office November 24, 1989 10:34 PM
You _must_ be referring to the C column of November. Well, now that just cut me to the ol' quick until I pulled out that column and my trusty tape ruler and did some measuring. By my measure, the column in question devoted 10 inches to linked lists and 14…
