bash questions

I installed gnu-win32 simply to run some csh scripts that I had on a
Solaris box. In the process of converting this script to bash I have
encountered the following problems...
1) set
It does not seem to do anything. I have been using declare instead. Is set
supposed to set variables?
2) let
let THREE=1+2
works fine in that
echo $THREE
responds with 3, but...
let OLTT=1<2
responds with...
2: no such file or directory
3) If I have a string of items such as...
declare ALIST="abc def ghi jkl mno pqr"
I can access items individually in a for command such as...
for ITEM in $ALIST; do
but is there a command or syntax that will let me access any one specific
member? I would
like to do something like...
declare THIS_ITEM=$ALIST[$INDEX]
4) test
I would like to make complicated arithmetic relational operations such
as...
test ($V1 -lt $V2) -a ($V3 -lt $V4)
but I am not getting the syntax quite right. Is there a way to do this?
Thanks... Eric Horowitz
