Device EntriesByte: 0 2 3DevicePhysical AddressBytes0-'MeaningDevice 10: The EBCDIC code for the logical device 10. This 10 iscompared to the 10 specified in the lOB during an open, and whenthey are equal, the device with that physical address is opened.2-3 Physical address: Byte 2 is the address of the lOB pointer for thisdevice. During an open, t~e main microprocessor moves byte 2 intothe logical I/O table, and oyte 3 to the lOB.ASCII Translate TableThe ASCII translate table contains two 256-bytes sections. The first section is usedfor input, to translate EBCDIC notation to ASCII. The second 256-byte section isused for output, to translate ASCII notation to EBCDIC. The hex value of eachcharacter is used as an offset into the appropriate translate table, and the originalhex value is replaced with the hex value at that offset.48
PARTITION AREAThe partition area contains the program executed by the main microprocessor andthe information required to execute these programs.AJI addresses shown in the following description are relative to the beginning of thepartition area.HexDisplacement00000040008001000120Variable(0200 if allbinaryregisters areassigned)Variable(pointed toin thepartitionlOB)Length inBytes (in Hex)40408080Variable (224if all binaryregisters areused)Variable(3584 if alldecimalregisters areused)VariableDescriptionPartition lOB (see Partition 108).Logical I/O table (see Logical I/O Table).Keyboard/display lOB (see Keyboard/Display108).Indicators 1000 through 1254, binary registersBRO through BR15, and/or decimal registersRO and R 1.
