Good.

The 0755 value would result in a long directory listing showing
the value -rwxr-xr-x for the permissions field. From an execution
point of view, a+rx sets the important permissions, but from a
security point of view, you need to ensure that the w permissions
are correct as well.

That's correct - the line beginning "exec xterm" says to replace
the current shell with a copy of xterm running the command after
the -e and xterm starts its own terminal window.

The chmod doesn't affect that - in this case, the script by
design starts its own window, as stated above, so ticking the
checkbox would cause the effect you specified.

It can be three or four numbers, and if four are specified, the
left hand digit specifies the security bits. For this task, you
definately want the security bits cleared, so 0755 specifies
exactly what is required.
To check this, do a long directory listing with `ls -l xjnos` and
check the permissions field (the left hand one). If there are any
's' characters in there, you have a probable security problem. As
stated above, the correct value is "-rwxr-xr-x" and is guaranteed
with 0755 as the value.
