Program works in real, not virtual

[Tonig00]

Thanks very much for your answer.

In my real calculator it works both modes: CAS and HOME.
But you are right in the virtual one, it works in HOME and not in CAS.


There are some things that still do not understand in the thread you suggest:
I have changed to
EXPORT ElM1(n,f1,f2)
BEGIN
LOCAL m1;
RETURN rowSwap(IDENMAT(n),f1,f2);
END;

And still gives me the same error in CAS

Well at least works in virtual-HOME and in any mode in real.

Thanks

Toni
