   That's the standard approach for C64, e.g. this is common:   
      
                   .addrs $0801   
                   .dd2  $080b           ;ptr to next line   
                   .dd2  $0014   
                   .dd1  $9e             ;SYS 2061 ($080d)   
                   .str  “2061”   
                   .dd1  $00   
                   .dd2  $0000   
      
   L080D           ldy   #$1e   
      
   In this case it's a HELLO program that starts when DOS boots, which IIRC   
   wouldn't work with a 'B' file unless you fiddled with something.
