AMSTRAD cpc 6128 User Instruction page 260

Each disc can be assigned a label, or name, and also a password. That password will
protect the directory itself, rather than the files named in the directory. The
individual files can also be assigned a password.
SET [NAME=ROLANDJ
SET [PASSWORD=SALLYJ
SET [PROTECT=ONJ
.... act on the default disc.
SET *.*[PASSWORD=SALLYJ
SET *.*[PROTECT=READJ
.... act on files on the default disc (the wild cards
* . *
used here indicate 'all files').
Date and time stamping can be activated by the I NIT D I R command (on Side 2 of
your system discs package). The commands:
INITDIR
SET [CREATE=ONJ .... or .... SET [ACCESS=ONJ .... and ....
SET [U P DATE = 0 N J .... together with .. "
DIR [FULL]
.... will initiate and display date and time stamping on the default drive. Typing in:
DATE SET
.... is then required each time
CP/M
Plus is started, to set the clock. Once set, the clock
will keep reasonable time, updated automatically by the 6128 and inspected by:
DATE .... and ....
DATE CONTINUOUS
WARNING
If passwords, disc labelling, or date and time stamping have been activated,
then it is recommended that the disc is NEVER subsequently written to by
AMSDOS or
CP/M
2.2, neither of which support these facilities.
