Combine Export and Local variables?

[Amer7]

Well I'm not sure, If the start value is Matrix, and if there are two operations with matrices it considers it automatically to be a matrix?

Code:

//PROGRAM START
EXPORT A1,A2;


EXPORT function1 ()
BEGIN
A1:=M1+M1;
A2:=M1-M1;

When I used this code, I didn't reserve it with MAKEMAT or MAKELIST
And the A1, and A2 matrices appeared in matrix editor with correct values
