Here you go:

ZCMD version, tested and works.

pawn Код:

CMD:fall(playerid,params[])
{
    new height;
    if(sscanf(params,"i",height)) return SendClientMessage(playerid,COLOR_RED,"Usage: /fall [height]");
    new Float:P,Float:O,Float:S;
    GetPlayerPos(playerid,P,O,S);
    SetPlayerPos(playerid,P,O,height);
    return 1;
}

and offc that other old sort, the strcmp command:

pawn Код:

if (strcmp(cmd, "/fall", true) == 0)
{
        new tmp[20],id;
        tmp = strtok(cmdtext, index);
        if (strlen(tmp)) return SendClientMessage(playerid,COLOR_RED,"Usage: /fall [height]");

        id = strval(tmp);
        new Float:P,Float:O,Float:S;
        GetPlayerPos(playerid,P,O,S);
        SetPlayerPos(playerid,P,O,id);


        return 1;
}

ZCMD command "installation", copy paste the first code inside the script, outside of any callback, i prefer at the bottom of the script, but OUTSIDE any callback.

i am sure you know how to put the other version in your script.

Tell me if they work
