Need help on Bash syntax

[Brad Appleton]

Ive been trying to get an answer to this for weeks. I hope someone in this
newsgroup will come through for me!!!!

I need to know everything about bash arrays (assuming they exist).
how does one do the following in bash (if possible):

1) set an array
2) unset an array
3) index an array (get a particular element)
4) modify an array element
5) index a subset of elements (like $argv[3-5] in csh)
6) modify a subset of elements

are there any other subtleties (like "set -A" versus "set +A" in ksh)?
Im getting desperate for this info -- please give me as much info as you 
can on bash arrays.

Also, in bash, what characters need to be escaped inside of double
quotes (including "\", '$' and '`' etc ...) in order to interpreted
literally by the shell (I need an exhaustive list).

I have somewhat of a time limit and I cant wait long enough for the 
documentation to arrive (and no one here has it).

Any and all help is much appreciated!!!!!!
