Title: ISO 7064/fr
| Old | New | Line | |
|---|---|---|---|
| 1 | + | La norme [ISO 7064](https://en.wikipedia.org/wiki/ISO_7064) spécifie un ensemble de systèmes de caractères de contrôle capable de protéger des chaînes contre les erreurs de saisie. | |
| 2 | + | ||
| 3 | + | ## Fonction StrMOD97 | |
| 4 | + | ||
| 5 | + | La fonction StrMOD97 peut encoder et vérifier la somme de contrôle selon ISO 7064 mode 97 10. | |
| 6 | + | ||
| 7 | + | ``` pascal | |
| 8 | + | ||
| 9 | + | function StrMOD97( s :String):integer; | |
| 10 | + | const | |
| 11 | + | modu = 97; | |
| 12 | + | var | |
| 13 | + | sx :String; | |
| 14 | + | isx,ic,p:Integer; | |
| 15 | + | begin | |
| 16 | + | p := Length( s ); | |
| 17 | + | while( p > 9 ) do | |
| 18 | + | begin | |
| 19 | + | sx := Copy( s, 1, 9 ); | |
| 20 | + | Delete( s, 1, 9 ); | |
| 21 | + | isx := StrToInt( sx ); | |
| 22 | + | ic := isx mod modu; | |
| 23 | + | s := IntToStr( ic ) + s; | |
| 24 | + | p := Length( s ); | |
| 25 | + | end; | |
| 26 | + | isx := StrToInt( s ); | |
| 27 | + | if isx >= modu | |
| 28 | + | then ic := isx mod modu | |
| 29 | + | else ic := isx; | |
| 30 | + | result := ic; | |
| 31 | + | end; | |
| 32 | + | ``` | |
