at(index: Integer64): MemberType;
The at method of the Array class returns a reference to the entry in the array at the position specified by the index parameter; for example:
firstCustomer := currentList.at(1);
The following examples show the use of the bracket ([]) operators to return an entry from an array.
firstCustomer := currentList[1];
display(): String;
vars
temp, alphaNumber : String;
entry : Integer;
begin
temp := self.faultNumber.String;
if temp.length > 4 then
alphaNumber := temp;
else
entry := 0;
while entry < 4 - temp.length do
alphaNumber := alphaNumber & (0).String;
entry := entry + 1;
endwhile;
alphaNumber := alphaNumber & temp;
endif;
return alphaNumber & " " & self.history.at(1)[1:100];
end;
If there is no entry at the specified index, an exception is raised.
