OK, that makes sense.
What I really wanted was to see if there was a way, regardless of the current range, to make the line specific.
e.g. if I have a routine start at 1100 (8 lines @ incr 10 to make range 1100-1170, I want a specific line 1190...if I add 5 lines and renumber 1100+ to 1100 incr 10, the range would become 1100-1220, that end line would now be 1290.
So, from what you've shown 1190!^90 would be reduced to 1170, then move out to 1260 when lines were added.
