rslogix 5000 commands

Hello,
i am just starting out in programming in rslogix 5000, i am having problems understanding the difference between COP (copy), MOV(Move), anf FLL(Fill) commands. the help file is ambiguous in explaining those commands. Can someone point me to material on the rslogix commands and the examples of their use? The help says they all do the same thing, but why would you have three commands that do the same thing?

Don't know if this will help but:

COP - copies blocks of data from one location to another

source -> destination
source -> destination
source -> destination

FLL - fills the words of a file with the source value

source -> destination
. ...........|
. ...........-> destination
. ...........|
. ...........-> destination

MOV - moves a source to a destination location

source -> destination
