Since Cetin alredy pointed out correct way of handling this issue
via global object holding object references to other forms,
here is quick & dirty :)

public oForm1,oForm2 &&begin of app 

*and then in init methods of both needed forms u stick this line ;
oForm1=this && first form
and 
oForm2=this && second form

After forms are instantiated via regular form calls

do form yourform1.scx && without name clause

you should be able to access both forms as easy as

oForm1.hide()
oForm2.caption='Form2 Caption'

and so for...

But my real advice is to sooner or later implement
something like Cetin adviced in his messages :)
