Thank you Ben,

what you wrote seems to be what I was looking for. If the EQU directive creates
an entry in the symbol table and the #define not, than debugging is only
possible
with the EQU directive.

Similar to the EQU directive is also the SET directive. Where can you use the
SET
in an efficient way?
