[S] Another pestering newbie question

I can't seem to find anywhere in the help files or manuals a way to do the
following:

suppose I have a model that in S Plus would be represented in the following
form:

group~x1+x2+x3+x4+x5+x6+x7+x8

x1 to x8 occur in a dataframe surrounded by other variables that may not be
interesting in this particular analysis, but x1 to x8 are adjacent columns
in the file.

In SAS I could do something like:

group=x1--x8,

in Systat:

group=x1..x8.

I realize I can extract the columns I need, put them in their own dataframe
and accomplish what I need, but is there some equivalent representation in
SPlus 4 that avoids having to pull these variables out of their original
file and enables some form of inclusive notation analogous to what SAS or
Systat uses.

Obviously if the variables were really named x1, x2, x3 etc, this wouldn't
be a big deal, but I'm building a model where the variables have meaningful
(and 6 to 8 character) names. I keep having to use the object browser to
get all the variable names right.

Thanks again for allowing me to intrude.
