Expression illegal in evaluator (& Access Violation)

Question

Im trying to process a plain text file (loaded into a StringList), by using class Tbb2uc but getting AV at calling function GetAddress.

  TArrayQuotePositions =          


        

Answer 1

It was a static array that i was over-indexing. The debugger cannot pinpoint the exact line so it was not obvious (for me):

function Tbb2uc.GetQuotePositions( aLine: string ): TArrayQuotePositions;
var
  i: integer;
  arraypos: integer;
begin
  for i := low(TArrayQuotePositions) to high(TArrayQuotePositions) do begin
    Farrayquotes[i] := 0;
  end;
  arraypos := low(TArrayQuotePositions);
  for i := 1 to length(aLine) do begin
    if aLine[i] = CHAR_FOR_COLLECT then begin         
      Farrayquotes[arraypos] := i;  //over-indexing, Farrayquotes: TArrayQuotePositions = array[1..4] of integer;
      inc(arraypos);            
    end;
  end;
  result := Farrayquotes;
end;

Sorry... indeed my question was far from complete.

Answer 2

You are accessing your stringlist out of bounds.

for i := 0 to SlInput.Count -1 do begin

 // ...(etc)

      addr := GetAddress(SlInput[i+2]); 

i is running to the full size of the list. You are indexing two higher than that.
