Explanation:
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. OPEN_FORM can be instructed for
the two forms to share the same database session and/or library data.
Note:
CALL_FORM
Runs an indicated form while keeping the parent form active. Oracle Forms runs the called form
with the same Run form preferences as the parent form. When the called form is exited Oracle
Forms processing resumes in the calling form at the point from which you initiated the call to
CALL_FORM.CALL_FORM can be instructed to hide or not hide the calling form, replace or notreplace the menu, open the new form in query only mode, share or not share library data.
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, Oracle Forms keeps the higher call
active and treats it as a call to the new form.
