Meaning
• Carry flag used in application instruction
• Used for the PR, PRC, BINDA, DBINDA, BINHA,
DBINHA, BCDDA, DBCDDA, or COMRD instruction
• Designates method to be used by search instruction.
• Data must be arranged for 2-part search.
• The sort instruction is used to designate whether
data should be sorted in ascending order or in
descending order.
• Goes ON when all data conditions have been met for
the BKCMP instruction.
• Goes ON when all data conditions have been met for
the DBKCMP instruction.
Turns on when the data to be compared by the DT or
TM instruction is not recognized as date data or time
detected
data, or the device (3 words) to be compared exceeds
the specified device range.
• Remains as originally set when OFF.
• CHK priorities updated when ON.
• ON when EI instruction is being executed.
Turns on when all data conditions are confirmed that
they are met by the DBKCMP instruction.
(Initial execution type program, scan execution type
program, stand-by type program executed from initial
execution type program or scan execution type
program)
Turns on when all data conditions are confirmed that
they are met by the DBKCMP instruction.
(Interrupt program, fixed scan execution type program,
stand-by type program executed from interrupt program
or fixed scan execution type program)
Turns on when all data conditions are confirmed that
they are met by the DBKCMP instruction.
(Interrupt program (I45) or Stand-by type program
executed from interrupt program (I45))
• Turns on only during one scan when the processing
of the COMRD or PRC instruction is completed.
completed
• Turns on only during one scan when the processing
completed
of the COMRD instruction is completed.
• Switches ON while a file is being accessed by the
SP. FWRITE, SP. FREAD, COMRD, PRC, or LEDC
instruction.
• Switches ON while a file is being accessed by the
SP. FWRITE, SP. FREAD, COMRD or LEDC
instruction.
• Switches ON while a file is being accessed by the
SP. FWRITE, SP. FREAD, COMRD or SP.DEVST
instruction.
• Turns ON while the ATA card or standard ROM is
being accessed.
performed • Turned ON when "OPERATION ERROR" is
suppressed for BIN or DBIN instruction.
