You said you used
DbgArray= array of integer

then I assume this declaration?
procedure ClrDebug(const panels: DbgArray);

If so the parameter is a dynamic array not open array and you cannot
call it with constant array:

  arr: DbgArray;
 ClrDebug([DbgKey, DbgCode1, DbgTx]); //Won't work
 SetLength(arr, ...);
 arr[0] := ...
 ClrDebug(arr);// This works

This on the other hand is an open array parameter:
procedure ClrDebug(const panels: array of integer);
