Using Find on Array of Record in PeopleCode

I've created an Array of Record, populated it with data from a table... later I need to do a find on it to get a record that I want.  The find isn't finding data that I know is in there.  I must be doing something wrong, but I can't locate an example of the find command used on an Array of Record.

Local array of Record &MY_array;

Local Record &MY_work_rec;

&MY_work_rec = CreateRecord(Record.MY_TEMP_TAO);

  &SQL_MY = CreateSQL(Select ... );

   While &SQL_MY.Fetch(&MY_work_rec)

      &MY_array.Push(&MY_work_rec);

      &MY_work_rec = CreateRecord(Record.MY_TEMP_TAO);
