Michael,

This must mean that the read/write permissions on ROUTE.SYS (and or the
directory that it is in) do not allow modification by the user 'mcidas'.

If the write permissions on ROUTE.SYS and SYSKEY.TAB are correct, then the
/mcidasdata/mcidas directory must not have the permission to allow the
write.  The questions to answer are:

o who owns /mcidasdata/mcidas

  cd /mcidasdata
  ls -alt

o does /mcidasdata/mcidas have the execute permission for group set.  The
  permissions should look like:

  drwxrwxr-x ... mcidas


  I.e., the directory should have owner read/write/execute; group
  read/write/execute; and world read/execute

Check the directory permissions and then see if you can write to
/mcidasdata/mcidas as 'mcidas':

cd /mcidasdata/mcidas
touch xxx
