It doesn't have to be a boolean, you can make it:

pawn Код:

new IsJailed[ MAX_PLAYERS ];

or even:

pawn Код:

static IsJailed[ MAX_PLAYERS ];

But, using "static" is really not required here. Statics are used for this if I recall:

pawn Код:

public Callback( params ) {
    for( new i = 0; i < 5; ++i ) {
        static var[ i ]; 
    }
    // You can still use the "var[ i ]" outside the loop if you use "static", if I remember. 
    var[ 0 ] = 0; 
    var[ 1 ] = 0; 
    var[ 2 ] = 0; 
    var[ 3 ] = 0; 
    var[ 4 ] = 0;
    return false;
}

and, if you used:

pawn Код:

public Callback( params ) {
    for( new i = 0; i < 5; ++i ) {
        new var[ i ]; 
    }
    // You now can't use the "var[ i ]"
    var[ 0 ] = 0; 
    var[ 1 ] = 0; 
    var[ 2 ] = 0; 
    var[ 3 ] = 0; 
    var[ 4 ] = 0;
    return false;
}

This will return errors, since the array didn't get passed out of the loop.
NOTE: This might not be what statics do, it's just what I think they do, I don't know if I remember right.
