LooperBreakIndex (Function)

In french: ZoneRépétéeIndiceRupture

Warning
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.

Example

// 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]
END

// Affectation du total
ATT_Total[FinRupture] = Total

// Passage à la rupture suivante
MaRépétition = FinRupture + 1
END
