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

EXPORT MMM:=256;

TEST(l):=
BEGIN
RETURN MMM*l[3];
END
#end

...but MMM is a Home variable when done this way.
Let's say I want to create a global CAS list, which can be indexed using []. How do I do that from a CAS program?

Export is to use first of the #cas #end or BEGIN END; block, with default values, like:

Code:

export MMM:=[[0,0],[0,0]];

In another part of the program you must use STO (or sto) to store a value in the var exported, like:

Code:

sto({varrow, varcol}, MMM);

not return, that you can use for other purpose...
When you store something, you can also read the variable in another part of the program (or other program)...

Is this your goal?
