Open file then read whole + count lines, next use fseek(handle, 0, seek_start); and read again whole file and if counter >= idx - 4 show line for player ;d

new str[128],lines,idx;
new File:F = fopen("file.txt",io_read);
while(fread(F, str))
    lines++;

if(lines > 3)
{
    fseek(F, 0);

    while(fread(F, str))
    {
        if(++idx > lines-4)
            print(str);
    }
}
fclose(F);
