Then why won't the following show a form when I comment out "PUBLIC frmForm"?

* myForm.PRG
PUBLIC frmForm
frmForm=CREATEOBJECT('subForm')
frmForm.Show()

DEFINE CLASS subForm AS FORM
CAPTION=[Form name needs to be public]
ADD OBJECT text1 AS textbox
text1.value=[Hello world]
PROCEDURE queryunload
this.release
ENDPROC 
ENDDEFINE
