Thanks for ideas on creating the points along a line.  One more thing 
to consider.  I have 1oo's maybe a 1000 of these to do and need to 
automate the interval calculation.  The points are numbered in 
sequence along the line so the total number of points I need to add is 
=(the last point number - the first point number)-1. I'm attempting to 
use ExpressionEvaluator to do the calculation but can't figure out the 
expression.

This represents aerial photography flight lines. The first photo taken 
is given a number and the rest follow in sequence. I have been given 
the first and last frame of each "run" and need to calculate the 
frames along the run.  

Thanks for helping out with this.
