If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc. You're using which OS? Groetjes, Berend (-: fido: 2:281/527.23 email: berend(a)beard.nest.nl

If you keep the whole database in memory, it's about the same as in Turbo Pascal: Use an array, an array of poiners, a linked list, a tree, or whatever. If your structure involves an array, GPC's "array schema" (according to ISO Extended Pascal) could be of interest for you: Type Foo ( n: Integer ) = array [ 1..n ] of Integer; FooPtr = ^Foo; Var f: FooPtr; i: Integer; ... New ( f, 42 ); for i:= 1 to f^.n do f^ [ i ]:= i mod 137; Dispose ( f ); GPC does not have a 64k limit, so you don't need to worry about, say, an array of pointers which is limited to 16380 pointers in Turbo Pascal. If you want to keep the data on disk, the following "dictionary" will be useful for you: Turbo Pascal GNU Pascal Assign See, for instance, the BPcompat package in ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/contrib (The next beta will have a built-in `Assign'.) reset (read-only) reset reset (read/write) update rewrite rewrite append extend Seek SeekRead SeekWrite SeekUpdate close close Hope this helps, Peter Dipl.-Phys.

THe GNU pascal compiler refuses to compile the gpc.exe, I use WIN95. Can't you guys just PLEASE compile the darn thing(with the executable) in MSDOS and put it on a ftp page?? ------------------------------------------------------ This message sent using the FirstClass SMTP/NNTP Gateway.

Random access database

I learned Pascal on VAX-Pascal (DEC VAX-VMS systems), and did allot of programming with Turbo in the 3.x to 5.5 days. Now I have a Linux system with GPC and want to write some database stuff using random access. My recent return to Pascal leaves me wanting to know how to do this with GPC compared to Turbo? pismo(a)mclv.net

According to Thomas Tan: > > THe GNU pascal compiler refuses to compile the gpc.exe, I use WIN95. Can't you > guys just PLEASE compile the darn thing(with the executable) in MSDOS and put > it on a ftp page?? What are you trying? Compile GPC with itself? It's written in C. I only can guess that the above is your polite way to ask for a binary distribution that runs under MS-DOS. Please read our FAQ list at http://home.pages.de/~gnu-pascal/gpc-faq.html There you can read that you can get a binary distribution ftp://kampi.hut.fi/jtv/gnu-pasal/binary/gpc-2.0.i386-djgppv201.zip (official version 2.0) or ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/ beta/binary/gpc-970714.i386-djgppv201.zip (beta version) for MS-DOS. The official version is also available from any SimTel mirror at the same place where you got the rest of DJGPP, subdirectory `v2gnu', file `gpc20b.zip'. You also might want to have a look at the CygWin version - see the online documentation http://agnes.dida.physik.uni-essen.de/gnu-pascal/gpc-doc.html chapter "Installation" for details.

Re: GPC Mail Lists in HTML

Hello, everybody. Hello, Lluis. Welcome to the GPC mailing list! According to Lluis de Yzaguirre: > [...] > We have a Sun SparcStation with SunOS 2.4; gpc is installed and works, > at least to compile "hello, world!"; but I will need help about system > calls, curses, file system, and so on. This is the right place to ask. > [GPC mailing list archives in HTML ...] > http://www.iula.upf.es/altres/pub/gpc/list2html/gpclist.htm Thanks a lot. This list looks very reasonable. When I will make over the GPC web site for the next time, I will set up a link. Here are some comments: * What about also listing it in time order? * Since there are programs scanning the WWW for "mailto:" URLs to send some crap there, maybe it's better not to put the e-mail address of each author under the article? I don't know ... * You probably know that the mailing list archives on Agnes are updated daily by a cron script. Are you doing the same? Best wishes, Peter Dipl.-Phys.

GPC Mail Lists in HTML
by Lluis de Yzaguirre 25 Sep '97

25 Sep '97

"Hello, world!" was the output of my first Pascal program; let me begin my way in this list with the same words. With this mail I will like to present the conversion to HTML of the list files, but I'll introduce my self. INTRODUCTION I'm a linguist working on "lingware" (Natural Language processing software) for the Catalan language (about 8 million speakers) at University "Pompeu Fabra" in Barcelona. I'm "pascaler" since 1982 (with Turbo-Pascal 2 for CP/M in an Apple II); I have lots of routines in Pascal [e.g. for generation all of the verbal forms in Catalan]: it means that I'm prisoner of my work, because migrating to a newer language implies to translate thousands of code lines; in addition, I like Pascal, so I'm not impatient to change it. At the moment, I use both Think P for Macintosh and Turbo P 7 (I develop in Mac and translate to TP7 for the windoides in my team); now it's time to go to Unix, because of some collaborators outside of our Institute. We have a Sun SparcStation with SunOS 2.4; gpc is installed and works, at least to compile "hello, world!"; but I will need help about system calls, curses, file system, and so on. GPC HTML LIST I don't like to abuse of your help, so the first thing is to read all the past mails. I found that ASCII reading is very annoying, so I wrote a conversion program and I'm studing all your q&a to the list. The conversion is already done and I think it could be useful for other "pascalers", so I put it to general disposition in my Web server as my first contribution to the GPC list. The URL is: http://www.iula.upf.es/altres/pub/gpc/list2html/gpclist.htm I'll apreciate comments (things to be improved, about the interest or nonsense of this work...) MAKING IT MORE EFFICIENT The avantage of the HTML version of the past lists is that you download every time only one message and you can print it if necessary very quickly. If you often access, I suggest to do as follows: 1.- Open one of the index files (v.g. "1997 by subject"). 2.- Save it "as source", i.e. as HTML file, with the name you like. 3.- Because of the line <BASE URL="http://www.iula.upf.es/altres/pub/gpc/list2html/"> in the file, you can open it as local file but with remote links. 4.- If it doesn't work, let me know. -- +-------------------------------------------------------------------+ !

Well then, let's add a 100ths count to timestamp... :) Seriously, is anyone doing any work on adding the proposed extensions to timestamp mentioned in the docs? An implemented us_Timer field would be random enough, I'd think. Of course, I already see this becoming a chicken-and-the-egg problem, because I don't know of a portable way to get system time readings of less than a second. But I would guess that all platforms offer the information in some form or another, and we could populate rts-time.c with a bunch of #ifdefs. -Kevin -- Kevin A. Foss --- kfoss(a)mint.net --

Hello, The boss is setting up Windows NT and I'll need to have gpc to compile code written on my Linux box. I looked through the documentation but couldn't figure out for myself which binary to grab. Can someone help me out? Thanks, Tom Thomas S. Dye, Ph.D. Home: 813 16th Avenue, Honolulu, Hawaii 96816. Voice (808) 734-2087.

There's a standard time function isn't there? The Sources to Persistence Of Vision Raytracer have a Random function that works the same across all platforms. See ya! Orlando Llanes
