Formatted Read to Storage (REBF)Source:REBFObject: 21oDfJo Read address: The address of the binary register that contains the address ofthe leftmost byte of data to read into the storage.fJ Format number: The number (hex 01-FE) of the format to use. For datadirected formatting, the * is specified and bits 16 through 23 contain hex 00.Data is moved into the register specified by the DCLBL parameters of the format.The number of bytes moved is determined by the LEN parameter, with editingcontrolled by the ED IT parameter of the format.170
Open a Data Set or Initialize Communications (OPEN/TOPEN/TINIT)Source:Object:TINIT (dsn)TOPEN (dsn)OPEN (dsn "BRn)0I I i I I I I22F F @( I I31I8 I 11 r 15 23ID fJIID Bits:8 0= TINIT, or OPEN for a diskette or printer.1 = TOPEN9-11 Always 100fJ Data set number: The number (hex 1-F) of the data set to be accessed.II Binary register address: The ID option for OPEN where the binary registercontains the storage address of the owner ID information. This optionalowner ID is stored on the volume label and is compared with the owner IDin storage. If the diskette is secure, the ID information in storage must matchthe owner ID on the volume label in order for the OPEN operation to execute.If the diskette is not a secure diskette, the binary register is ignored.The owner ID information may be up to 14 characters long; if less than 14characters are used, the owner ID must be followed by a blank (hex 40). Ifthe binary register is omitted, or if this is a TINIT or TOPEN instruction,this byte contains hex 00.Note: Two commas must precede the binary register if it is included. If theregister is omitted, the commas are also omitted:TINIT establishes the communications link and begins the line connection forcommunications.TOPEN sets the open flag in the communications lOB to indicate that the lOB isopen.OPEN sets the open flag in the diskette or printer data set lOB to indicate that thedata set is open. It adds the address of the data set lOB to the lOB chain, andvalidates the .DATASET parameters in the lOB.When the open has completed, the data set's HDR1 label will be located in the first128 bytes of the physical buffer except for pointer I/O and SCS data sets that havethe SW or E RS parameter specified in the .DATASET control statement. For a labelupdate data set, the VOL 1 label will be saved instead of the HDR1 label. The opcode byte in the data set lOB is replaced with hex 00. If there is an external statusfor insufficient physical buffer size (3430), or two physical buffers specified withunequal sizes (3435), or if any group 7 warning message is presented, the minimumnumber of 128-byte blocks required for sufficient buffer size is placed into hex 78of the data set lOB. If any other external status occurs, this number is not placedinto the lOB.Object Code Instruction Format 171
