Here's a simple example (as far as I understood what you said):

Let's say you have your scripted /goto command which looks like:

pawn Код:

new cmd[256], idx;
    cmd = strtok(cmdtext, idx);
    if(strcmp(cmd, "/goto", true) == 0)
    {
        new tragetplayer, tmp[128];
        tmp = strtok(cmdtext, idx);
        if(GetPVarInt(playerid, "NotAbleToGoto") == 1)
        {
            SendClientMessage(playerid, -1, "You are not allowed use this command!");
                                   return 1;
        }
        else if(!strlen(tmp))
        {
            SendClientMessage(playerid, -1, "Usage: /goto <id>");
                                   return 1;
        } 
        targetplayer = strval(tmp);
        if(targetplayer == INVALID_PLAYER_ID)
        {
            SendClientMessage(playerid, -1, "ERROR: Player is not connected!");
            return 1;
        }
        else
        {
            new Float:x, Float:y, Float:z;
            GetPlayerPos(targetplayer, x, y, z);
            SetPlayerPos(playerid, x, y, z);
        }
        return 1;
    }

Well, let's make a command which disable /goto for a certain player:

pawn Код:

if(strcmp(cmd, "/gotoff", true) == 0)
    {
        new targetplayer, tmp[128];
        tmp = strtok(cmdtext, idx);
        if(!strlen(tmp))
        {
            SendClientMessage(playerid, -1, "Usage: /gotoff <id>");
                       return 1;
        }
        targetplayer = strval(tmp);
        if(targetplayer == INVALID_PLAYER_ID)
        {
            SendClientMessage(playerid, -1, "ERROR: Player is not connected");
                                   return 1;
        }
        else
        {
            SetPVarInt(playerid, "NotAbleToGoto", 1);
        }
    }

And if you'd like to make a command that enables /goto, you would simply do as I did with /gotoff. But change SetPVarInt(playerid, "NotAbleToGoto", 1); to SetPVarInt(playerid, "NotAbleToGoto", 0);
