Zugriffsverletzung ??? Ich kappiers nicht!

[faux]

Hallo!

Also ich hab grad ein totales Blackout!
Ich kappiers nicht. Wiso tritt denn da eine Zugriffsverletzung auf?

Delphi-Quellcode:

unit Unit2;

interface

uses SysUtils, AgentObjects_TLB;

const
  LMax = 2;

type
  TCommandAction = (ccTrue, ccFalse, ccNoCommand);

function Inizialize(const Command: String; AgentItem: IAgentCtlCharacterEx): TCommandAction;
function ActCommand(Commands: Array of String; AgentItem: IAgentCtlCharacterEx): TCommandAction;

implementation

function Inizialize(const Command: String; AgentItem: IAgentCtlCharacterEx): TCommandAction;
var
  Commands: Array[1..LMax] of String;
  i, j: Integer;
begin
  j := 0;
  if Length(Command) > 0 then
  begin
    for i := 0 to Length(Command) - 1 do
      if Command[i] <> ' ' then
        Commands[j] := Commands[j] + Command[i]
      else
        if j < Lmax then
          inc(j)
        else
          break;
    Result := ActCommand(Commands, AgentItem);
  end
  else
    Result := ccFalse;
end;

function ActCommand(Commands: Array of String; AgentItem: IAgentCtlCharacterEx): TCommandAction;
begin
  if Commands[1][1] = ':' then  //Hier tritt sie auf.... hm....
  begin
    result := ccTrue;
  end
  else
    result := ccNoCommand;
end;

end.
