";" is a way of saying to compiler that we reached end of statement.

pawn Код:

new a;
new b[32];

You can create two variables without having to repeat "new" keyword, using a comma

pawn Код:

new a, b[32];

But you have a typo, and did

pawn Код:

new a; b[32];

Change it to comma and you're good to go.
