David, how do this compare to PicForth integrated disassembler?

Here is an example of PicForth disassembly (excerpt from
i2cloader.fs):

        ; name: add-to-buffer
        ; max return-stack depth: 1
0x0661  0823    movf    0x23,w
0x0662  0384    decf    0x04,f
0x0663  0080    movwf   0x00
0x0664  2604    call    0x604   ; any-!
0x0665  0AA3    incf    0x23,f
0x0666  0008    return  
        ; name: reset-i2c-buffer
        ; max return-stack depth: 0
0x0667  3025    movlw   0x25
0x0668  00A3    movwf   0x23
0x0669  0008    return  
        ; name: read-eeprom-data
        ; max return-stack depth: 2
0x066A  2667    call    0x667   ; reset-i2c-buffer
0x066B  0826    movf    0x26,w
0x066C  00C5    movwf   0x45

0x0672  0AC5    incf    0x45,f
0x0673  0BC6    decfsz  0x46,f
0x0674  2E6F    goto    0x66F   ; read-eeprom-data + 0x005
