pawn Code:

// Define when to split the text into another line!
#define EX_SPLITLENGTH 118

stock SendSplitMessage(playerid, color, final[])
{
    new buffer[EX_SPLITLENGTH+5];
    new len = strlen(final);
    if(len>EX_SPLITLENGTH)
    {
        new times = (len/EX_SPLITLENGTH);
        for(new i = 0; i < times+1; i++)
        {
            strdel(buffer, 0, EX_SPLITLENGTH+5);
            if(len-(i*EX_SPLITLENGTH)>EX_SPLITLENGTH)
            {
                strmid(buffer, final, EX_SPLITLENGTH*i, EX_SPLITLENGTH*(i+1));
                format(buffer, sizeof(buffer), "%s ...", buffer);
            }
            else
            {
                strmid(buffer, final, EX_SPLITLENGTH*i, len);
            }
            SendClientMessage(playerid, color, buffer);
        }
    }
    else
    {
        SendClientMessage(playerid, color, final);
    }
}

Usage:

pawn Code:

SendSplitMessage(playerid, color, msg);

EDIT:

The above code is just more or less an example and may or may not be really fast processing your strings. Your probably better off using split.
