No-one seems to have mentioned this restriction as a potential source of problems:
You can assemble the DCB macro into a program that resides above the 16 MB line, but the program must move it below the line before using it. Except for the DCBE, all areas that the DCB refers to, such as EXLST and EODAD, must be below the 16 MB line.
