Getting the number of vertice on a CLINE

Once in a while we get a CLINE that has a number of vertice in a straight line.  Sometimes they're wirebonds.  I'm trying to write some code that will determine the number of vertice on a cline. 
I already have the code to grab the clines that I want, I just need help working my way through them to find which ones have more than a beginning and an end point.
Also, when it finds one that meets the criteria, is there a "merge" command that will merge all of the segments into one long segment?  I could delete and replace the cline, but most of the time the cline has properties on it already.

Thanks,

Mark
