hash table is like ini file

e.g

add data in:
ini file: /writeini file.ini NAME ITEM DATA
Hash tables: /hadd -m NAME ITEM DATA

read or get data

ini file: $readini(file.ini,NAME,ITEM) return DATA
Hash tables: $hget(NAME,ITEM) return DATA

take look at /help $hget

u have many parameter for $hget

$hget(NAME,0).item return the total number of item for NAME

$hget(NAME,1).item return the first item
$hget(NAME,1).data return the first data

e.g: NAME = Trev ; ITEM = testitem ; DATA = data test ok
1 2 3-
NAME ITEM DATA
/hadd -m Trev testitem data test ok

now u can try this

//echo -a $hget(trev,testitem) => return "data test ok"
//echo -a $hget(trev,1).data => return "data test ok"
//echo -a $hget(trev,1).item => return "testitem"
//echo -a $hget(trev,0).item => return "1"

now take look at /help $hget u'll find more about it :)
