>How does STOP work?  Is MODIFY similar?

Almost identical; both chain a new CIB to the CSCB and post an ECB.
The differences are:

 1. ECB CC
 2. CIB verb
 3. No text from STOP command

>Does either schedule an RB to a task? 

No.

>Which is older, STOP or MODIFY?

They are essentially contemporaneous; certainly both arrived in the
mid 1960's.
