an example of the program the code is this one that reports a syntax error the name of the program is
test():=
BEGIN
RETURN;
AND;
when I put it like this
#cas
test():=
BEGIN
RETURN;
AND;
#and
then in this code structure it gives the syntax error, this only happens when I put # in line 1, when I put it in cas mode this is happening after the 2.2 update. Could you help me please?
