diferences between emulated and real hp prime

[kain_x_x]

Hi guys
I'm having problems with hp programing.
I made a program in computer executing it in emulated hp prime but once i charge it into real hp prime i've got several sintax error. ( I upload the program to both HPs using conectivity kit).
I'm having problems like:

Can't define a matrix of zeros with:
MAKEMAT(0,n,m); where n, and m are local variables.

can't define in a FOR loop the elements of a matrix:

FOR i FROM 1 TO fila DO

l(i,1):=a(i,1); (SOME SINTAX ERROR HERE)
u(i,i):=1;
END;


any ideas why i'm having those problems?
Regards
