Correct, I'll expand on it though as your description is slightly vague.

Declaring a variable such as:

pawn Код:

new Var;

is simple a single variable. You can only store a single piece of data in this variable (without messing about with binary and stuff).

Declaring a variable as:

pawn Код:

new Var[MAX_PLAYERS];

is called an array. An array can store multiple pieces of data related in 'slots' relative to the array itself. It's a little like doing:

pawn Код:

new Var1;
new Var2;
new Var3;
new Var4;
new Var5;
//etc...

(but, it uses slightly less memory if I remember correctly).
You can access (and set) data from/to an array by knowing the 'slot'. This could be stored in a variable or otherwise. Example:

pawn Код:

Var[playerid] = 1; //Where playerid is declared as an integer.
//Make Var[playerid] become 1.

pawn Код:

Var[0] = 0;
//Make the slot 0 of var equal to 0.

pawn Код:

for(new i; i < sizeof(Var); i++) //In this example, "sizeof(Var)" gets the array size.
{
    Var[i] = 100;
}
//This loop will make all the slots in the array called "Var" equal 100.

I hope you can understand better now.
