HexDisplacement39Length inBytes (inHex)DescriptionKeyboard Flags:BitoMeaningSet to 1 by the keyboard/display microprocessorwhen the object code programissues the request for error operation(KERRST). Reset to 0 when the objectcode program issues the request error resetoperation (KERRCL). The application programshould not change this bit.The keyboard/display microprocessordetected a keying error. The bit is turnedoff when the reset key is pressed. The applicationprogram should not change this bit.2 Keyboard is open for data entry. Set whenan ENTR command or RESUME instructionis executed. Cleared when a CNENTR commandis executed or when an external statuscondition is detected. The application programshould not change this bit.3 The cursor is within a field.4 If a keying error occurs, the keyboard/displaymicroprocessor checks the status line.If the status line is not displayed, it displaysit. When the error is reset, it replaces thestatus line with the extra line from therefresh buffer.o Do not check the status line. Normally, nOchange is made in this bit by the applicationprogram. If the application program doeschange this bit, it should not change it whilean ENTR command is being processed.5 Status line is displayed. Indicates that theextra I ine must be displayed when the erroris reset. The application program should notchange this bit.6 A mismatch error occurred while verifyinga constant insert field. The applicationprogram should not change this bit.7 Set by the keyboard/display microprocessorwhen the perform keyboard operation (hex11) is issued by the object program. It indicatesthat the EBCDIC code came from theobject code program; therefore, the microprocessordoes not check the keyboard bitmap. The application program should notchange this bit.Main Storage Data Areas 67
