Hi Peter;

 

On confirming this, you are absolutely correct in the case of adding two words together. Subtracting two words is done correctly. Adding or subtracting a byte to a word are also both done correctly. In the case of adding two words, Bean simply has the order backwards, the '_lsb needs to be added before adding the '_msb.

 

Here is the compiled results on adding/subtracting two words as well as a word with a byte:


[code]
  
   342  0000  0215        ADD WordOne_MSB,WordTwo_MSB    ;WordOne = WordOne + WordTwo
        0001  01F5
   343  0002  0214        ADD WordOne_LSB,WordTwo_LSB   
        0003  01F4
   344  0004  0603        ADDB WordOne_MSB,C            
        0005  02B5
   345                  
   346  0006  0214        SUB WordOne_LSB,WordTwo_LSB    ;WordOne = WordOne - WordTwo
        0007  00B4
   347  0008  0703        SUBB WordOne_MSB,/C           
        0009  00F5
   348  000A  0215        SUB WordOne_MSB,WordTwo_MSB   
        000B  00B5
   349                  
   350  000C  021C        ADD WordOne_LSB,ByteOne        ;WordOne = WordOne + ByteOne
        000D  01F4
   351  000E  0603        ADDB WordOne_MSB,C            
        000F  02B5
   352                  
   353  0010  021C        SUB WordOne_LSB,ByteOne        ;WordOne = WordOne - ByteOne
        0011  00B4
   354  0012  0703        SUBB WordOne_MSB,/C           
        0013  00F5
   
Regarding the IFDEF, I have not had the time recently to mess with that, but I hope to look into it soon.

Thanks for your interest.

Cheers,

Peter (pjv)
