You have to find some standard library (dependend of your operating system) which contains something equivalent to clrscr. On DOS and OS/2, look into the EMX documentation libref.doc (it is a C library, but never mind -- GPC.GUIDE explains how to use it with GPC). With Linux, write the terminal escape sequences to the screen to emulate functions of CRT -- see the etc/termcap file for details. Or you can wait a little: I am writing a system-independent replacement for crt, graph, and the whole Turbo Vision (but in graphics mode). (Some people say, there would be no need for it, but I won't stop. :-) I hope to be ready for the first release (of only the crt part) this year. > ps. Is there also a manual for it (not gpc.guide).. I am afraid, no. But read README.TURBO, there are some things documented, how GPC differs from Turbo. Bye, Peter -------------------------------------------------------------------------------- Dipl.

GPC problem..
by Martin Moerman 03 Dec '95

03 Dec '95

I have a problem when using gpc.. I was a big fan of borland pascal (turbo pascal 3 to 7).. When i use gpc i can't use the command clrsrc (clear screen). Normaly in pascal i have to do (uses dos;), how can i solve this problem in gpc. ps. Is there also a manual for it (not gpc.guide).. Martin mamoman(a)xs4all.nl

GNU Pascal Binary
by root 01 Dec '95

01 Dec '95

I've just installed Slackware Linux 3.0 on my system and I'm trying to install the GNU pascal compiler. Unfortunately, the only version of GCC I have is 2.7.0. I don't know where to find GCC 2.6.3 to run with GPC. Do you know where I could find this, or know where I could find a GPC compiler compatable with 2.7.0? Any help would gladly be appreciated. Thanks, Greg Sibley n9345955(a)cain.lake.cs.wwu.edu <== mail to this address

emx libs
by tdunbar＠gserver.grads.vt.edu 30 Nov '95

30 Nov '95

when i compile: program t(input,output); type s1=string(10); var s:s1; begin readln(s); writeln(substr(s,2,3)); end. with gpc on solaris or linux, it compiles fine. when i compile with emxgpc, i get: ... ld -o t.exe /emx/lib/crt0.o -L/emx/lib/st -L/emx/lib C:\DOS\cce00002 -lgpc -lgcc -lc -lc_app -lc -lgcc -lemx -los2 -lemx2 rts-string.c:144 (/emx/lib/gpc.a(rts-string.o)): Undefined symbol ___gcc_bcmp referenced from text segment rts-string.c:188 (/emx/lib/gpc.a(rts-string.o)): Undefined symbol ___gcc_bcmp referenced from text segment rts-string.c:190 (/emx/lib/gpc.a(rts-string.o)): Undefined symbol ___gcc_bcmp referenced from text segment am i using the wrong emx package? (other things compile fine..just problems working with strings) where can i get libs compatible with the latest emxgpc? -- Thomas Dunbar 540 231-3938 (fax 3714) http://gserver.grads.vt.edu/

gpc - questions

Robert Bosch GmbH Erbach, 30.11.95 IA1 / ESP4 Peter Kraemer-Eis Postfach 1162 D-64701 Erbach Tel.: 06062/78-463 Germany Fax.: 06062/78-771 Dear Mr. Virtanen, in our company, we have developed the software for a robot controler. Up to now, we used the National NS32000 family as target-cpu. Except of the hardware-near parts, our present software is written in NS-cross-pascal. The whole software for the robot-controler needs 2 MByte code and is split into about 200 files (modules). Now we are forced to replace the target-cpu by an intel-cpu (i486 or i586) and we hope, that most of our present software is portable to your GNU-Pascal. For a test, we have installed 'Linux SuSE August 95', which includes your GPC version 1.1 (2.6.3). First results are quite promising, but there are some questions: (1) Is there any reference manual (in addition to the GPC.GUIDE, which is too short, to work with it)? If yes, how can I get it? (2) Is there any possibility, to avoid the case-sensitivity of the names of variables/procedures? Our present software is completely written in capital letters and therefore we have problems when debugging with GDB. (3) Is there any restriction to the number of import/export of variables or procedures? (4) How can I get the source-files of your GPC? I havn't found them on the CD-Roms of 'Linux SuSE August 95'. Best regards, yours Peter Kraemer-Eis

Binaries for OS/2 and DOS
by A.A. Olowofoyeku 28 Nov '95

28 Nov '95

Hi Can you please point me to the location of the OS/2 and DOS binaries (with the Borland compatibility stuff)? I presume that there is a ready-to-run package somewhere (lost most of my saved mail recently, and so I can't trace earlier posts). Do I have to download GCC as well? Thanks.

I have some shareware programs (a Windows installer and uninstaller, and a command interpreter for Windows), and my users are demanding Win32 versions. MS have moved the goal posts (-->> Win32) and I have no choice other than follow, or lose my users to competitors, some of whom already have Win32 versions, while I am still waiting for Borland. > > I think you can get Prospero by e-mail; > > tpm2info(a)prospero.demon.co.uk > > To buy or to look at or to steal?

Hmmmm .... I am not sure you would get anything from Prospero that you couldn't get by just reading the EP specifications, so you don't really need Prospero at all. It is not cheap either. If you are prepared to review the compiler for some computer magazine, they might send you a free review copy. They sent me one, for my review in the Pascal Magazine. -- Warmest regards, The Chief --------- Dr. Abimbola A.
