Request Keyboard Error Mode (KERRST)Source: KERRST (BRa BRb)I10 I I 1 0 Object: C7 @I IS§l 1~E0 8I15 I 23 / 31D D IJo Keyboard operation number: The number that the main microprocessorstores in the keyboard/CRT lOB starting at hex displacement 1 F.D Message: The address relative to the start of the partition of the binaryregister that contains the main storage address of the message to move tothe status line refresh buffer.IJ Attribute mask and control information: The address of the binary registerthat contains the attribute mask in byte 0 and control information in byte 1.Byte0Bit0-23456702-7Meaning if 1Attribute Mask:ReservedColumn separators displayedBlinkUnderscore lHighlight lReverse image lControl Information:0= Do not check for display of status line.1 = Display status line if it is not currently displayed.Start in column 1. (If bit 1 = 0, start in column 3.)Message length minus 1, up to 63. If 63 is specified, itindicates 0 bytes.llf bits 5, 6, and 7 equal 111, data will not be displayed.282
This operation places the keyboard in software error mode. When the keyboard/display is in software error mode, all data keys, function keys, and command keysequences are ignored. However, if the KEYOP instruction for operation hex 11(perform keyboard function) is issued, the function is performed as long as thekeyboard is in an appropriate state.Bits 3-7 of the attribute mask are exclusively-ORed with bits 3-7 of the rowattributebyte (which determines the display of the row) for the top row of the screen.If the status line is not displayed on the screen, the extra line will have the indicatedattributes.Bytes are moved from the address specified to the status line. The bytes are translatedthrough the display translate table, and attributes are translated and passed.The bytes moved from storage overwrite the original status line data, and theoriginal status line data destroyed.If the status line is currently being displayed when this instruction is executedthe indicated message is displayed in column 1 or column 3, according to byte 1,bit 1 of the control information. If the status line is not being displayed, themessage is not displayed unless byte 1, bit 0 is 1.This operation is invalid if the keyboard/display is already in software error mode,or if issued from an unattached background partition.Reset Keyboard Error Mode (KERRCL)Source: KERRCL (BRa)I IObject: C7I I ~F I {1 0 I I000 8 ] 15 ] 23 31DfJD Keyboard operation number: The number that the main microprocessorstores in the keyboard/display lOB starting at hex displacement 1 F.fJ Attribute mask and control information: The address of the binary registerthat contains the attribute mask in byte 0 and control information in byte 1.See keyboard operation OE for the format.This operation takes the keyboard/display out of software error mode. It is validonly after a KERRST operation, and only when issued from an attached partition.When this operation is executed, if an ENTR command is outstanding and bits 2-7of the control information do not equal zero, the field shift, hex display, currentposition counter, insert morJe, and positions remaining in current field counter arerestored in the status line. An attribute change is allowed, as for KERRST. Bits2-7 of the control information specify the number minus 1 of positions to replacewith blanks when the KERRCL operation is executed.Object Code Instruction Format 283
