Under certain conditions, I use the "hack of the hidden form"...

If you only need your persistent variables for a client-side usage AND your application runs inside a frame AND at least one of your frames is not refreshed (e.g. menu or logo) AND JavaScript is enabled on your clients:

1. Build an HTML form in your fixed frame, with an <INPUT> field for each persistent variable; this form has a NAME, but no ACTION; for each <INPUT> field the TYPE is HIDDEN, so your form won't be visible.
2. From your PL/SQL packages, you can build JavaScript in your application frame; this script can write some values in your <INPUT> fields (the syntax is parent.framename.document.formname.controlname.value), and thereafter another script will be able to read these values.

Remark: if an user refresh the entire document, your values will be lost.
