So you're setting it to:

pawn Код:

for(new i=0;i<sizeof(vInfo[iID][FlightNR]);i++)
{
    new RandomFlight = random(2);
    switch(RandomFlight)
    {
        case 0:
        {
            format(vInfo[iID][FlightNR], sizeof(vInfo[iID][FlightNR]), "%s%s",vInfo[iID][FlightNR],RandomLetter());
        }
        case 1:
        {
            format(vInfo[iID][FlightNR], sizeof(vInfo[iID][FlightNR]), "%s%i",vInfo[iID][FlightNR],RandomNumber());
        }
    }
}

Also note that random(x) returns a MAXIMUM of x-1.
