I have four forms,viz, X,Y,Z,AA

X is the main form. I want to open the other forms form the main and to return back to main from the subsidiary form,e.g.

Form Y is used to search date wise data . After completing this I want return to main . In form Y I have one command button,
named "CMDQUIT"

In the click event of"CMDQUIT' I wrote:

thisform.release()
do form start name myform &&linked
READ EVENTS  && if I omit read events the main form is not visible.
<\pre>
The window type of the form is 'MODAL'

But this is not happening. The main form is opening but without releasing form Y.

Please help me.
