David,
If you set the form's Data Entry property to Yes on its property sheet, then
this happens automatically, but will not allow you to view/ edit other
records.
Or if you want to intermittently open the form in Data Entry mode, you'd use
the 5th argument in the DoCmd statement on the calling form.
DoCmd.OpenForm "MyForm", , , , acFormAdd
Or if you want to immediately go to a new record but be able to view/ edit
existing records, you can either code it in the calling form:
DoCmd.OpenForm "MyForm"
DoCmd.GoToRecord , , acNewRec
OR
You can use the 'called' form's On Open or On Load event
DoCmd.GoToRecord , , acNewRec
HTH,
Brian
