fy the memory block to be saved. Enter the start and end addresses in the manner

described in the D command explanation. Any start and end addresses of the

installed memory can be specified; however, if the monitor area is saved, a file

which cannot be coded is generated on the cassette tape. This is because the moni-

tor saves itself, so check sum codes necessarily mismatch.

This is not desirable.
