LooperBreakIndex (Function)
In french: ZoneRépétéeIndiceRupture
From version 28 (75), LooperBreakSubscript is kept for backward compatibility. This function has been replaced with LooperBreakIndex.
Returns the index of the break header and footer for a given break in a Looper control:
  • The index of the header for a given break also corresponds to the index of the first row in this break.
  • The index of the footer for a given break also corresponds to the index of the last row in this break.
// Le champ Zone répétée ZR_Factures liste les factures de chaque client
// Une rupture sur chaque client est effectuée
// Le bas de rupture contient le champ TotalFacture
// lié à l'attribut ATT_Total
// Ce champ affiche le total de toutes les factures de chaque client
MaRépétition is int = 1 // Début du champ Zone répétée
DébutRupture is int // Indice du haut de rupture
FinRupture is int // Indice du bas de rupture
Indice is int // Indice des répétitions
Total is int // Total de chaque rupture
// Calcul des totaux pour tout le champ Zone répétée
WHILE MaRépétition <= ZR_Factures.Occurrence
// Indice de la rupture courante
DébutRupture = LooperBreakIndex(RUPT_HautClient, MaRépétition)
FinRupture = LooperBreakIndex(RUPT_BasClient, MaRépétition)
// Parcours des répétitions de la rupture courante
// pour calculer le total
FOR Indice = DébutRupture TO FinRupture
Total += ATT_Valeur[Indice]
// Affectation du total
ATT_Total[FinRupture] = Total
// Passage à la rupture suivante
MaRépétition = FinRupture + 1
<Result> = LooperBreakIndex(<Break header/footer> [, <Index>])
<Result>: Integer
  • Index of the header/footer break specified in the break containing the row at index <Index>,
  • 0 if an error occurs. To get more details on the error, use ErrorInfo with the errMessage constant.
<Break header/footer>: Character string
Name of the break header or footer to be used.
This parameter can correspond to:
  • the name of the break header or break footer directly.
  • <Name of Looper control>.<Name of break header/footer>
<Index>: Optional integer
Index of one of the rows in the desired break.
If this parameter is not specified, the index of the header/footer break specified in the break containing the current row is returned.

LooperBreakIndex can be used on:
  • a Looper control based on a data file,
  • a Looper control populated programmatically.

Using the LooperBreakIndex function
