But I see that the algorithms given in the Spec like
Algorithm to determine the bounds of a paragraph containing a certain 
character in a complex file
Algorithm to determine paragraph properties for a paragraph in a complex 
file
all refers to the Fc , ie to get the PAP or CHP of a particular character 
you have to track its Fc  & using this Fc you have to get the Papx or 
Chpx..
I am bit confused to arrive at a way to do this.

Thanks & Regards

PlexOfCps is more of a utility structure for reading and writing from the
file. We are not concerned with FCs anyway, we only care about CPs because
FCs are based on file locations and the file location may change.

How is everything going? I am currently working on Tables and Lists.
