i was reading the intro to amx scripting thread ..and i have a couple of doubts :

1.what is the use/meaning of this
read_argv(1, Arg1, 23)
read_argv(2, Arg2, 3)
2.why we have to Convert the health from a string to a number?
can you please tell me what is use/meaning of the following statements

if (Arg1[0] == '@')
{
new Team = 0
//Check which team was specified.
//Note that we start from [1], this is okay
// it just means the @ isn't included
if (equali(Arg1[1], "CT"))
{
Team = 2
} else if (equali(Arg1[1], "T")) {
Team = 1
}
new players[32], num
//This function will fill the players[32] variable
// with valid player ids. num will contain the number
// of players that are valid.
Thanks in advance
