Description
oth_x can be AND'd (see and operator (bitwise)) with the filemode retrieved by the built-in procedure getfilemode to determine whether users not belonging to the same group as the owner of a file or directory has permission to execute the file or search the directory.
Example
For example the simple program below asks for a filename and then displays the file permissions for users who not belong to the same group as the owner of the file.
program OtherUsersPermissions(input, output);
var
s : filename;
mode : integer;
isdir : boolean;
begin
write('Enter filename:');
readln(s);
s := fexpand(s);
getfilemode(s, mode);
isdir := (mode and dir_bit) <> 0;
write('Other permissions :');
if (mode and oth_r) <> 0 then
write(' Read');
if (mode and oth_w) <> 0 then
write(' Write');
if (mode and oth_x) <> 0 then
if isdir then
write(' Search')
else
write(' Execute');
writeln;
