Hello Chris.

try this:
       aset = 0..23;

als try this

       aset = 7..16;

sets of integers aren't packed they are bit-aligned on 0.
so bits in the set that represent the elements look like this:

 07 06 05 40 03 02 01 --
 15 14 13 12 11 10 09 08
 23 22 21 20 19 18 17 16
 -- -- -- -- -- -- -- 24

with your enumerated type
however

 CH>   bset = (rlogon,   {1}

 ord(rlogin) == 0

 CH>           fnodeletion); {24}

 ord(nodeletion) == 23

In that way it looks like a aet of 0..23 to the part of the compiler which 
handles sets.

 07 06 05 40 03 02 01 00
 15 14 13 12 11 10 09 08
 23 22 21 20 19 18 17 16

and that only takes 3 bytes
