The system variable SysVar.arrayIndex contains a number:
You can use SysVar.arrayIndex as any of these:
Record mySerialRecPart serialRecord: fileName = "myFile" end 10 zipCodeArray CHAR(9)[100]; 10 cityStateArray CHAR(30)[100]; end
Furthermore, assume that the arrays are initialized with zip codes and city-and-state combinations.
The following code sets the variable currentCityState to the city and state that corresponds to the specified zip code:
currentZipCode = "27540"; if (currentZipCode in myRecord.zipCodeArray) currentCityState = myRecord.cityStateArray[SysVar.arrayIndex]; end
After the if statement, SysVar.arrayIndex contains the index of the first zipCodeArray element that contains the value of "27540". If "27540" is not found in zipCodeArray, the value of SysVar.arrayIndex is 0.
