Simple Scripting language

I am trying to make a simple scripting laungange in qt that you can change variables from c++ in the script and the return it back so far this what I have:

Code:

QString Script = "def SH_Script Print hello hey; Print hey;";
 
    if(Script.startsWith("def SH_Script", Qt::CaseInsensitive))
    {
        Script.replace(QRegExp("def SH_Script"), "");
        QStringList Lines = Script.split(";");
        QStringList Words[Lines.count()];
 
        for(int i = 0; i < Lines.count(); i++)
        {
            Words[i] = Lines.at(i).split(" ");
 
            for(int w = 0; w < Words[i].count(); w++)
            {
                if(Words[i].at(w) == "Print")
                {
                    for(int h = 0; h < Words[i].count(); h++)
                    {
                        if(Words[i].at(h) == "Print")
                        {
                            Words[i].removeAt(h);
                        }
                    }
 
                    QString output;
                    for(int a = 1; a < Words[i].count(); a++)
                    {
                        output += Words[i].at(a) + " ";
                    }
 
                    qDebug() << output << endl;
                    output = "";
                }
 
                else if(Words[i].at(w) == "def")
                {
                   //creates a new varible
                }
 
                else if(Words[i].at(w).startsWith('$'))
                {
                   //refers to a varible
                }
 
                else if(Words[i].at(w).startsWith("--"))
                {
                    Words[i].clear();
                }
                else if(Words[i].at(w) == " ")
                {
                    //reconizing space instead of errors
                }
                else if(Words[i].at(w) == "")
                {
                    //reconizing space instead of errors
                }
                else
                {
                    qDebug() << "syntax error at line:" << i;
                }
             }
         }
    }
    else
    {
        qDebug() << "Not decarled as a SH Script";
    }

Any suggestions or help would be great
