[Coco] Error codes on SECB

Correcting myself here :(
After examining the Extended Basic unravelled book, I find that (1) the NE
Error is defined in Extended absic, and (2) it seems to be only used by the
DLOAD(M) command. (which is reasonable, I guess). However, since I have
never heard of anyone successfully using the DLOAD(M) command, it is safe to
say that the error is exclusive to DECB.
