{Modifications
Date: 4/1/98 RAB/ISL
Description: Added procedure SelectVital(FontSize:integer; idx: integer)
    To be able to pass the row index into the form.  This will enable the vital
    entry form to open the apropriate line on this form (If this screen is opened
    by the vital entry screen)

Date: 4/9/98 RAB/ISL
Descriotion:  Added button and click event to call vital entry screen.

Date: 4/9/98 RAB/ISL
Descriotion:  if Idx passed into procedure SelectVital is '99' then the botton to
  call the vital entry screen will be disabled.

Date: 4/23/98
By: Robert Bott
Description: Set position of form to poScreenCenter.
Date: 4/23/98

Description: Forced an update after returning from vital entry form.

//Modifed: 6/23/98
//By: Robert Bott
//Location: ISL
//Description of Mod:
//  Moved code that verifies valid provider and visit from fvit into fVitals.
//   now found in procedure TfrmVitals.btnEnterVitalsClick(Sender: TObject);
//   formerly in procedure TfrmVit.FormActivate(Sender: TObject);
