Running a a function with parameter in Command line

So, Instead of calling function with parameter in Command line. I changed my aspect to get it done my requirement.

Here is the function which i used and it's working fine.

function InitiateExecution()
{
      var count_CL_Parameters = BuiltIn.ParamCount(); 
      
      var static_String_TC_NameAndEnv = "TestCaseName=";
      var currentTestCasenameAndEnv = "",arr_TC_Parameter = null;
      
      try
      {
            if(count_CL_Parameters > 3)//This part is for running from Test Complete/Execute Commandline
            {
                  for(var a = 0 ; a <= count_CL_Parameters ; a++)
                  {
                        if(aqString.Find(BuiltIn.ParamStr(a),static_String_TC_NameAndEnv,0,true) != -1)
                        {
                              currentTestCasenameAndEnv = BuiltIn.ParamStr(a);
                              arr_TC_Parameter = currentTestCasenameAndEnv.split("=");
                              if((arr_TC_Parameter != null) && (arr_TC_Parameter.length == 2))
                              {
                                    //CL_TestCaseName, CL_Environment are global variables
                                    CL_TestCaseName = GetCellValue.getNameFromValue(arr_TC_Parameter[1]);
                                    CL_Environment = GetCellValue.getCountFromValue(arr_TC_Parameter[1]);
                                    isCommandLine = true;
                                    driverscript();
                                    break;
                              }
                              else
                              {
                                    throw "TestCaseName not found"  
                              }                   
                        }
                  }
            }
            else//This part is for running from Test Complete/Execute manually
            {
                  isCommandLine = false;
                  driverscript();
            }
      }
      catch(ex)
      {
            ShowMessage("Error Occured: \n Parameters are missing : Format should be <Test Compelte/Execute Path> <Project Suite path> /r /e [TestCaseName=<value>[EnvironmentName]] \n Or Unkown error : " + ex.stack);
      }
}

 It is may not be understandable since this function is part of Customized Data-driven framework which we are having in place.
