Accessing Individual entries in a post register
 

Hi,

I calculate some quantity and load it into post registers (Say register 4). What I need to do is to check the individual values in this register 4 and to change some of them depending on a control statement (through an 'if' condition).

1. How do you access individual entries in a post register?

2. After manipulating these entries, how do you write back to the same locations in the same post register?

Appreciate you help,
