Also, if you want to avoid all files being executable, there is 
   exe=system
— use the DOS “system” attribute to indicate which files are executable.

Execute bits don’t really affect security at all, at best they prevent you from accidently executing things that likely
 won’t execute anyway.  In this case there likely is no security but that’s a function of having an unverifiable file 
system.

    Needless to say (but I'll say it), both of these options are highly insecure, essentially making the execute bit 
useless (as it gets applied to all files on the medium).
    If you don't have a disk with a file system that provides proper permissions (and user/group ownership) you can 
always copy the executable to /dev/shmem and run it from there.

    An alternate way is to put "dos exe=all" on the startup line of the devb-* resource manager.  For example,
    
    # devb-eide dos exe=all qnx6 sync=optional cam quiet
    
    BSP's seem to favor this approach - perhaps because it works with "automount".  But both ways work.
