- Set the file attributes as given.
The file attribute string can contain the characters 1,2,3,4,r,s,a,n and m. The
meanings of these are:
- The CP/M "user attributes" F1-F4. CP/M does not
assign any meaning to these attributes, though MP/M does.
- The file is read-only. This is the same as using
cpmchmod(1) to revoke write permissions.
- The file is a system file. This attribute can also be set
- The file has been backed up.
- Reset all attributes to zero. So the string "n1r"
resets all attributes and then sets F1 and Read-Only.
- Attributes after an m are unset rather than set. The string
"12m34" sets atttributes F1 and F2, and unsets F3 and F4.
Upon successful completion, exit code 0 is returned.
Any errors are indicated by exit code 1.
