No, it's about whether a chunk of code is designed to return a value -- that's a function; a subroutine may accept a parameter but [usually] doesn't return anything (if it does it is limited to one byte).  Here are two very simple examples:

[code]
SUB TX_BYTE
  SEROUT TX, BaudMode, __PARAM1
  ENDSUB

FUNC RX_BYTE
  SERIN RX, BaudMode, tmpB1
  RETURN tmpB1
  ENDFUNC[/code]

Note that -- in this [SX/B v2.0 compliant] form -- the RETURN keyword is only used with the function.
