Procedure Test
    Boolean iSuccess
    Handle hoSb
    Boolean iRemoveFlag
    String sResult

    Move False To iSuccess

    Get Create (RefClass(cComChilkatStringBuilder)) To hoSb
    If (Not(IsComObjectCreated(hoSb))) Begin
        Send CreateComObject of hoSb
    End

    // Load a file that contains this string:  0123456789ABCDEF
    Get ComLoadFile Of hoSb "qa_data/txt/remove_chars.txt" "utf-8" To iSuccess

    // Return "56789A" from the string.
    // if removeFlag is True, the returned string is also removed from the sb.
    Move True To iRemoveFlag
    Get ComGetRange Of hoSb 5 6 iRemoveFlag To sResult

    Showln sResult
    Get ComGetAsString Of hoSb To sTemp1
    Showln sTemp1

    // Output is: 
    //
