Thank you for you answer.

I am more confused now, because the behavior of the global APPEND 
directive seems inconsistent between a cfg file and the command 
prompt.

In a cfg file, there are multiple ways to override the global append. 
In the command prompt, there seems to be no way at all to override 
it.

In a cfg file, an APPEND command after a LABEL directive seems to 
override the global APPEND (is there any way to merge them?), whereas 
in the command prompt I am having problems to achieve the same - 
instead of overriding the global append, it is always "merged". Thus, 
the initial question in my first email.

The following is a simple example.

 *** syslinux.cfg start ***
PROMPT 1
APPEND /dir/

LABEL ls_label
COM32 /ls.c32
 *** syslinux.cfg end ***

>From the command prompt, I am trying to run "ls.c32 /", but it fails 
(it seems to understand the command as "ls.c32 //dir/").

So...

1_ From the command prompt, is there any method to override the 
global APPEND "/dir/"?

2_ In the cfg file, is there any method to merge a global APPEND with 
a specific APPEND stated after a specific LABEL (kernel)?

TIA,
Ady.
