How to pass a value from a procedure to another?

Hi everybody,

I'm trying to make a skill that renames all the selected objects in the layout with a value that I insert in the form and merging it with a counter.

For example: If I have 30 copied resistors (I1, I2,I3,..., I30), I want to rename them R0.1, R0.2, ..., R0.30 .

At first try I made a single procedure that creates the form and renames. That seemed to work correctly but, if I press the button "cancel" in the form, the procedure continues and renames all the selected objects with the value of the counter (1,2,3...,30).

So I decided to make two procedure, one for the creation of the form and another for the execution of the renaming.

There is only one problem I can't really figure out: how can I pass the name, that I wrote in the form, to the procedure of execution?  

Hope someone can help me.

Bye bye :)

Here it is my form:

/*CREATE FORM*/
procedure( change()
let((myform changeName)        


/*CHECK LAYOUT VIEW*/

if( (geGetEditCellView()~>cellViewType != "maskLayout") 
 then hiDisplayAppDBox(
   ?name 'errorbox2
   ?dboxBanner "Errore"
   ?dboxText sprintf( nil "La procedura funziona solo con Layout Window")
   ?dialogType hicErrorDialog
   ?buttonLayout 'Close  
   ?dialogStyle 'modal
   ) 
 )
  


changeName=hiCreateStringField(
                ?name 'changeName
                ?prompt "Inserire nome"             
  ?defValue ""
  ?editable t
  ;?callback "esec()"
    )

 
 hiCreateAppForm(
            ?name 'myform
            ?formTitle "Change Instance Name"
           ?fields list( changeName )
     ?callback "exec(changeName~>value)"
  )




hiDisplayForm(myform)


)
)


/*EXECUTION RENAMING*/

procedure( exec()
let( (changeName nome num)

nome = changeName~>value

if( (rexMatchp("symbol" buildString(geGetSelSet()~>viewName)) == nil) && (rexMatchp("lay" buildString(geGetSelSet()~>viewName)) == t)
  then for(i 1 geGetSelSetCount()
 
   sprintf(num "%d" i)
   geGetSelSet()~>name = strcat(nome num)
   geSelectNextInSelSet()
  
 )
 )

)
)
