Try
CALL SYND.BAT
instead of just SYND.BAT

ouch, your autoexec is messed up.

Do this (and don't load the autoexec.bat you're laoding) in the autoexec section of dosbox.conf:
mount C C:\dosbox
mount A A:\ -t floppy
c:\xkeyb\keyb be.key
c:\syndicate\synd.bat
exit

(ok, the only problem I see is that syndicate is too long a word, shorten the directory by a character and change the above autoexec accordingly)
You really don't have to have such a complicated batch system as you have (it really serves no purpose).
Also your language might be covered by the Dosbox internal keyboard command, so probably no use to load the extra one you have.

c:\syndicate\synd.bat
exit

Again, this will only work if you use CALL SYND.BAT

Can you tell me why? Of course I belive you, I'd just like to get educated why this works and the other way doesn't 😀

It's work gereat with call, thanks.

I've modified the autoexec.bat like this :

1mount C C:\dosbox 
2mount A A:\ -t floppy 
3y: 
4cd\xkeyb\ 
5call keyb BE.key 
6mount x C:\dosbox\syndicate\ 
7x: 
8call SYND.BAT 
9exit 

and it's working (it's a part of a program i made for my job, i test it with games... )

Thanks a lot.

ps : with call, dosbos wait for the end of the program before continue the execution of the bat file (-> i think it's that).

there can only be one batchfile active at one time. (without call)
so if you start one without call then it can not return to the original batchfile.
so all lines below the synd.bat will be skipped

I see, thanks for the explanation.

@kate: but you really could trim down your mountings 😀

It's nothing dosbox specific btw., just some nice msdos oddity.
Think i never knew about this back in the dos days...

Yeah, I figured. I saw this back in the days in some batchfiles but never looked into why the batches were called...

If i've good memories, with ms-dos you can call different batch file without using the call function.

Yes but you need to CALL them.
