You'd generally use an array for this.

pawn Код:

stock IsChoiceVehMid(playerid)
{
    stock const gChoiceVehMid[] = {
    435,
    441,
    449,
    450,
    464,
    465,
    501,
    537,
    538,
    539,
    564,
    569,
    570,
    584,
    590,
    591,
    594,
    606,
    607,
    608,
    610,
    611
    };

    for(new i=0; i<sizeof(gChoiceVehMid); i++)
    {
        if(gChoiceVehMid[i] == choicevehiclemid[playerid]) return 1;
    }
    return 0;
}

Not tested, and I wasn't sure what to call the function/array etc. because I have no idea what the hell it is.

Simply replace your code with this:

pawn Код:

if(IsChoiceVehMid(playerid))
