Don't define IFJ6, IFJ7 etc but rather have a numeric vector of flexible length 
JVER (say),   [[ Note that JVERSION is a character string which displays as 5 
lines ]]

if. 7 = {. JVER do. ....
if. 6 0 2 -: 3 {. JVER do.

 ... 
        Could we avoid cruft like this in the future by defining a
system global "IFJ7" (or, even better "ISJ7" so that statements using it
will avoid "if. IF...") in J7?  Or does someone have a better way of dealing
with this?
