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 say

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.
