Thanks Ken. So, to modify Nick's example, if my program is written in 8.2 but I want to let the 9.0 users use the new level options, could I sayIn Stata 9 you say syntax ... , ... Level(cilevel) ...

program myprog

version 8.2

local oktype = cond(`c(version)' < 9, "integer `c(level)'", "cilevel")

syntax ... , ... Level(`oktype')

Eventually I may write a version for Stata 9, but in the meantime it seems a shame to cripple the program for Stata 8 users if all you are doing is adding support for the new level options. There are lots of other user-written programs that use integer levels, so programmers who are so inclined could make one quick change in them without having to set version to a higher number.
