Have you considered adding the firmware build version to that symbol or to a
new one?
__RCX = 2
__FIRMWARE=3.21
This would facilitate creation of portable, work-around code that would
accomodate an end-user who hasn't updated their firmware (or has a reason not
to). It could also be useful in comparing code functionality side-by-side on
two firmware versions.

| (...) This first define (__RCX = 2) will happen automatically in NQC when you select RCX 2.0 as the target for compilation. Selecting an RCX 1.0 target will cause the symbol to be defined as 1. (...) I hope I don't have to add a __FIRMWARE symbol... (...) (27 years ago, 9-Apr-00, to lugnet.robotics.rcx.nqc)
