Hi,
when I try to debug a DOS-Executable, I often get the message
"Unable to register server". Usually I can start the Debugger 3 or 4
times, but then the next time this Error-Message occures.
If the DOS-Debugger works, it is not possible to switch
between source and application, also the System always crashes
when I step into a function that expects keyboard-input, e.g. getch()
or kbhit().
Any suggestion?
Thanks,Alex.

If you are truly working with Watcom 11.0 (the original) and not 11.0a,
11.0b, I would strongly suggest that you upgrade to 11.0c. This is free.
Here we are:

See
http://www.openwatcom.org/download/download_licenses.html
See
http://downloads.openwatcom.org/ftp/11.0c/c_readme.txt
for what has been fixed.

How are you debugging your app? There are 2 choices:

Choice 1
======

1. Open 2 DOS Command boxes
2. In one type

WINSERV /tr=rsi

2. In the other type

BINW\WD /tr=win yourapp.exe

Choice 2
======

For graphical apps, the above won't help. You need to boot Windows 98 in
MSDOS mode and then do

BINW\WD /tr=rsi yourapp.exe

Thank you,

well,to be honest,i first tried to debug the DOS-app by clicking the
IDE-Debug-Icon, so your suggestion to boot in MSDOS mode and start
WD from the DOS-Prompt was the most important help for me...
I also upgraded to 11.0c and had no more system-crashes.

So everything is fine, excepting one point (i'm afraid this is another
boring newbie-question..):
My programm tries to read from a file that i created. But fopen() always
returns NULL (error-message:no such file or directory). This problem
only occures while debugging from the DOS-Prompt, via the IDE-Icon
the File can be opened. I tried debugging with the /localinfo switch,
without success,i'm not sure what to do,
Greetings,
Alex

I created the file with fopen("scores.sc","w"), so the filename is in
6.2 format,
