extern varibales

Hello together,
I have this problem of global variables again. But in my case I need a
varibale, a string, which should be known in all my modules. I put some of m
y
functions out in modules which I call when I use them but all these function
s
also need some directory-pathes as strings. At the time I tell this function
s
this pathes with parameters but this is very long windet.

Does anybody know another solution. Do we have in perl something like a scop
e
EXTERN linke in C ?

Gruss Christian
