Suppressing unable to resolve reference to parameter... message

Question

We have converted our applications to Oracle 9I (Internet) from Oracle 5 (Client Server).
We force a closing of an extra browser window by creating a .pll with a customized function called close_browser which runs close.htm and then does an exit_form to replace exit_form. We have forms call other forms, if the form is called, then it checks a forms parameter called parameter.pr_called. We want to just modify the library and not modify 100s of forms but :parameter.pr_called does not exist in a number of forms but we need to check parameter.pr_called with a NAME_IN in the library just in case it is called so we don't close the browser window if the form is a called form. It would then simply exit form and go back to the original form. When we check for name_in('parameter.pr_called) = 'Y' to check for this condition, we get unable to resolve reference to parameter pr_called.
We have tried changing message levels, but that only works for error messages and not messages. There seems to be no programming way to do a find_parameter for a form parameter. Any suggestions on how to prevent the message from appearing. We would not want to modify all the forms.
Thank you,

If you want to add this parameter to all your forms in batch - this is simple to do with the Java API - here's some sample code.
package oracle.forms.jdapi.demos;
import oracle.forms.jdapi.*;
public class AddParam
  public AddParam(String formName, String parameterName, String parameterValue)
    try
      // Open the module - this implicitly starts JDAPI
      FormModule form = FormModule.open(formName);
      System.out.println("Processing " + form.getName());
      // see if the parameter already exists
      ModuleParameter param = null;
      try
        param = ModuleParameter.find(form, parameterName);
      catch (JdapiException cjdex)
        System.out.println("Parameter not present needs creating...");
      if (param == null)
        // create the required Param
        param = new ModuleParameter(form,parameterName);
        param.setParameterDataType(JdapiTypes.PADA_CHARACTER_CTID);
        param.setMaximumLength(3); //assuming Y/N, YES/NO??
        param.setParameterInitializeValue(parameterValue);
        System.out.println("Parameter created...");
        //we've made a change so save...
        form.save(formName);
        System.out.println("Form Saved...");
      else
        System.out.println("Parameter already exists...");
      form.destroy();
      Jdapi.shutdown();
    catch (JdapiException jdex)
      System.out.println(jdex.toString());
   * @param Pass the name of the Form as an agument to the class
  public static void main(String[] args)
    String paramName = "PR_CALLED";
    String paramDefaultValue = "N";
    AddParam addParam = new AddParam(args[0], paramName, paramDefaultValue);
    System.exit(0);
}
