    Updates the parent 'IF' statements by inserting 'NOT' after 'IF' for each 'ELSE' keyword found.
    
    This function processes a DataFrame where some rows have the keyword 'ELSE'. For each such row, 
    it identifies the corresponding parent 'IF' statement using the 'Conditional_Seq' column. If the 
    parent 'IF' statement does not contain 'NOT', the function inserts 'NOT' immediately after 'IF'. 
    It then removes all rows with the 'ELSE' keyword from the DataFrame and resets the index.

    Parameters:
    -----------
    df : pandas.DataFrame
        The DataFrame containing the 'Sequence', 'Conditional_Seq', 'Keywords', and 'Statement' columns.
    
    Returns:
    --------
    pandas.DataFrame
        The updated DataFrame with modified parent 'IF' statements and no 'ELSE' rows.

    This function processes a DataFrame containing COBOL code and uses the keywords 'IF', 'EVALUATE', 'WHEN', and their respective 'END' statements
    to determine the appropriate indentation level. It returns a list of COBOL statements with sequence numbers and correct indentation.

    Parameters:
    -----------
    df : pandas.DataFrame
        The DataFrame containing COBOL code with 'Sequence', 'Keywords', and 'Statement' columns.
