replacing variable with same variable

I have a perl script where I match on phrase to add
something after
that phrase:
$line=~s/PILOT_INC=4,/PILOT_INC=4, NGHBR_SRCH_MODE = 0,/g;

However, the "4" can be variable, say, anything
between 2 and 8.

I'd like to do something like this:
$line=~s/PILOT_INC=d,/PILOT_INC=d, NGHBR_SRCH_MODE = 0,/g;
Of course this won't work.

Do I need to first save the number into a variable and then
put that
variable into the regex replace phrase or can it be done
within the
global search and replace regex line above?

regards, David

Or you can try the following:

$line=~s/PILOT_INC=([2-8]),/PILOT_INC=$1, NGHBR_SRCH_MODE =
0,/g;
