I think the "< 0" is due to Comet using left-to-right evaluation  
and pyz80 using proper operator precedence.  You could try using -- 
nobodmas with pyz80 to force the old behaviour, or use the simple  
expression Andrew suggested to me:  defs -$\256

I'll check this - with --nobodmas pyz80 should be completely  
compatible with comet files.

(If the code is already 256-byte aligned, doesn't Stefan's version  
leave a 256-byte gap?)

The other option is to use a new pyz80 extension, whose intent should  
be much clearer:

        DEFS ALIGN 256

HTH,
Andrew
