Open and Close of multiple forms

Hi, I want to make a "Next" button on my_form1 such that it shall call my_form2 when it is pressed by users.

and a "Back" button on my my_form2 such that it shall call my_form1 when it is activated. 

the functions looks like this : 

procedure(MY_form1_Init()

my_form1 = axlFormCreate(...'My_form1_action ... )

axlFormDisplay(my_form1)   ) ; end initialization function

 ;action function

procedure( My_form1_action(my_form1) 

case(my_form1->curField

...

("next" ... axlFormClose(my_form1)

my_form2 = axlFormCreate( ...'My_form2_action ... )

axlFormDisplay(my_form2) 

) ; end next 

... 

) ; end case

) ; end my_form1_action

At the "next", after closing my_form1, my_form2 is open. if i do the same for "back" at my_form2 (close my_form2 and

open my_form1), i suppose this will result in nested loop... how shall i go around with this? such that i can ensure my_form1 is

closed completely (exit from the action function) before the form2 is open... thx in advance.
