The only thing that would be usefull is, if we can differentiate between

But it's a big difference if the result was -10 or +10.
 

If you were willing to define the weights to result codes within your 
app, you could generate both positive and negative weights with 
different test names using a bitmask.  It all depends on how variable 
your weighting system is and whether or not it mattered to step them 
(which it likely would not).  For instance, you could do the following:

   SPAMCHK-PASS(5)   bitmask   -4     "C:\IMail\Declude\spamchk.exe"    
0    -5
   SPAMCHK-PASS(3)   bitmask   -2     "C:\IMail\Declude\spamchk.exe"    
0    -3
   SPAMCHK-PASS(1)   bitmask   -1     "C:\IMail\Declude\spamchk.exe"    
0    -1
   SPAMCHK-FAIL(1)    bitmask   1      
"C:\IMail\Declude\spamchk.exe"    1    0
   SPAMCHK-FAIL(3)    bitmask   2      
"C:\IMail\Declude\spamchk.exe"    3    0
   SPAMCHK-FAIL(5)    bitmask   4      
"C:\IMail\Declude\spamchk.exe"    5    0
   ...

This is different from how Sniffer would work because it sounds like you 
only desire one final result, but you want to have it return a weight 
plus an indication of pass or fail.  You would create a routine that 
mapped the desired weights to a whole bit value in the result code.

The idea of weight- and weight+ would be more appropriate to your needs 
however, and it would require no change on your part.  Sorry to have 
stolen your thread with an alternative idea.  Implementing weight- and 
weight+ would be much easier to implement it would seem, but limited in 
applicability.

I'm not sure if signed variables could do this for us by using a bitmask
tecnique. And I'm also not sure if it's tecnicaly possible to use bitmasks
since the current interface for external tests is the DOS exit-code. As I
know a value between 0 and 255 ... nothing more.
 

I believe that this is only a limitation of batch files with the 
ERRORLEVEL variable.  While that would give you potentially 8 values, I 
don't believe that the limitation is anywhere near as severe if it 
exists at all with other environments.  WScript seems to support 4-byte 
integers, although they are half negative and half positive so that 
might limit them to being 16 bits/bitmap results without a function to 
remap these in Declude, but I'm not sure if that is required, and I 
don't think that 16 positive and 16 negative results would be a 
hindrance for people.
