GoSub...Return Statement

Calls a subroutine that is indicated by a label inside a Sub or a Function. The statements following the label are executed until the next Return statement. Afterwards, the program continues with the statement that follows the GoSub statement.

GoSub label[:]

label: A line identifier indicating where to continue execution. The scope of a label in that of the routine it belongs to.

The GoSub statement calls a local subroutine indicated by a label from within a subroutine or a function. The name of the label must end with a colon (":").

  Sub/Function foo
      ' statements
      GoSub label
      ' statements
      Exit Sub/Function
  label:
      ' statements
      Return
  End Sub/Function

Jika program menemukan pernyataan Pengembalian yang tidak didahului oleh Pergi ke Sub, LibreOffice Dasar mengembalikan pesan kesalahan. Gunakan Keluar Sub atau Fungsi Keluar untuk memastikan bahwa program meninggalkan Sub atau Fungsi sebelum mencapai pernyataan Pengembalian berikutnya.

Contoh berikut menunjukkan penggunaan Pergi ke Sub dan Pengembalian. Dengan menjalankan bagian program dua kali, program menghitung akar kuadrat dari dua angka yang dimasukkan oleh pengguna.

Sub ExampleGoSub
Dim iInputa As Single
Dim iInputb As Single
Dim iInputc As Single
    iInputa = Int(InputBox("Masukkan nomor pertama: ","NumberInput"))
    iInputb = Int(InputBox("Masukkan nomor kedua: ","NumberInput"))
    iInputc=iInputa
    GoSub SquareRoot
    Cetak "Akar kuadrat dari";iInputa;" adalah";iInputc
    iInputc=iInputb
    GoSub SquareRoot
    Cetak "Akar kuadrat dari";iInputb;" adalah";iInputc
    Exit Sub
SquareRoot:
    iInputc=sqr(iInputc)
    Return
End Sub
