FILE ATTRIBUTES

21       The  file  attribute  string can contain the characters 1,2,3,4,r,s,a,n
22       and m.  The meanings of these are:
23
24       1-4    The CP/M "user attributes" F1-F4.   CP/M  does  not  assign  any
25              meaning to these attributes, though MP/M does.
26
27       r      The file is read-only.  This is the same as using cpmchmod(1) to
28              revoke write permissions.
29
30       s      The file is a system file.  This attribute can also  be  set  by
31              cpmchmod(1).
32
33       a      The file has been backed up.
34
35       n      Reset  all  attributes  to zero.  So the string "n1r" resets all
36              attributes and then sets F1 and Read-Only.
37
38       m      Attributes after an m are unset rather  than  set.   The  string
39              "12m34" sets atttributes F1 and F2, and unsets F3 and F4.
