Complex matrices in programs

I get "Unmatch control word" error message.

Actually, I just discovered that I can't run any CAS programs any more, even the default template "new CAS program" without any alteration returns

program([],[],[0 0]).

Resetting the calc also doesn't help. Is this occurring because of the "insufficient memory message"?

I can confirm the behavior with complex matrices in a non-CAS program. For CAS programs, I tried:

Code:

#cas
TEST():=
BEGIN
local l:=[[(1,2)],[(3,4)],[(5,6)]];
return l;
END;
#end

This program ran fine in Home and CAS view (Firmware 6940).

Regarding complex matrices -- the parser actually converts any matrix into a list combined with a ListToMat() command. However, it seems to choke on complex matrices. You can see this by creating the following program that does nothing but declare and initialize two variables: a real value and a matrix and then debug it.

Code:

EXPORT TEST2()
BEGIN
local a:=0;
local l:=[[1,COS(a)],[4,5]];
END;

This only occurs for matrices that do not consist of purely real numbers (in this case "COS(a)" not a real number in syntax).
