i see no problem with your code

you can also do that like this
VB Code:
  1. Private sub FORM1_load()
  2.     hitung
  3.     test
  4. end sub

of

VB Code:
  1. Private sub FORM1_load()
  2.     hitung
  3. end sub
  4.  
  5. Private sub TEST()
  6.     tetxbox1.text="BLAH BLAH"
  7.     ' and change some other control on FORM`
  8. End Sub
  9.  
  10. 'on module part with name ABCD
  11. public sub Hitung()
  12.     'do whatever
  13.     text
  14. end sub
you need not to use call since these are just procedures and not functions
