How do you assign a global var in a CAS function?

[webmasterpdx]

Never mind! I think I got it figured....

If you do the following...

#cas
TEST(l):=
BEGIN
m:={5,4,3,2,1};
RETURN l[3]*m[2];
END
#end

m is now a global CAS variable of type list.

Also, if the program was a Home program (defined with EXPORT), then assigning m the same way (not declared as LOCAL), it would be a Home variable of type List...and global. i.e. EXPORT is only needed for global variable definition if outside a program definition.
