there is no config.sys to do that.

We put the message there to see if somebody/something actually used that call.

thank you!

i searched the web for this error message, but without success. now im looking for a debugging feature in dosbox to find a solution. im not a programmer, so im looking for a debugging howto.

btw:
in an earlier version of dosbox the program budenberg works. but not all parts of the programm - only the first menue.
useing version 0.63 the first menue doesnt work (dosbox exits with the described error message) but the other program parts dont. 🙁

that's the call
your program is the first we know that uses this call

1	    21h capitalize string
2		DS:DX -> string to capitalize
3		CX = length of string

Shouldn't be that hard to add. It was never needed though.
if you can compile dosbox yourself go to src/dos/dos.cpp:834
and replace that line with a ;
it's a work around and maybe it works.

thank you - now it works!

maybe you can put some code to one of the next versions, so that this fix has not to be done in the sourcecode of the debian packages. I'm a maintainer of an austrian school project that is trying to create a linux terminalserver/samba solution for schools, based on debian. (www.slixs.at) Now I'm trying to emulate some dos programs (eg budenberg) to work in a linux terminalserver environment. - Next is to make sound work over network. but this ist not that important.

could we get into contact so i could notify you if i coded support for it so you could test if it works ? (e.g. not leads to any crashes ?)

Yes I would appreciate!
here is my mail address
