Call From-New Form-Open Form

Call Form: Runs an indicated form while keeping the parent form active. Form Builder runs the called form with the same Runform preferences as the parent form. When the called form is exited Form Builder processing resumes in the calling form at the point from which you initiated the call to CALL_FORM.
PROCEDURE CALL_FORM (formmodule_name VARCHAR2, display NUMBER, switch_menu NUMBER, query_mode NUMBER, data_mode NUMBER, paramlist_name/id VARCHAR2);

New Form: Exits the current form and enters the indicated form. The calling form is terminated as the parent form. If the calling form had been called by a higher form, Form Builder keeps the higher call active and treats it as a call to the new form. Form Builder releases memory (such as database cursors) that the terminated form was using.
Form Builder runs the new form with the same Runform options as the parent form. If the parent form was a called form, Form Builder runs the new form with the same options as the parent form.
PROCEDURE NEW_FORM (formmodule_name VARCHAR2, rollback_mode NUMBER, query_mode NUMBER, data_mode NUMBER, paramlist_name/id VARCHAR2);

Open Form: Opens the indicated form. Use OPEN_FORM to create multiple-form applications, that is, applications that open more than one form at the same time.
PROCEDURE OPEN_FORM (form_name VARCHAR2, activate_mode NUMBER, session_mode NUMBER, data_mode NUMBER, paramlist_id/name PARAMLIST);
