Define a variable

[aborruso at spaziogis.it]

Dear user,
my map file and my template file and ... are in a folder with a long path
(something like
/lotus/domino/data/domino/spaziogisit/mapserver/cartsic/symbols/line.sym);
can I define a variable like mapserver=
/lotus/domino/data/domino/spaziogisit/mapserver/  to point more easily to
my work folder??
Thank you,

Andrea
