BIND area format and DSECT

The ISTDBIND DSECT can be used to set up or examine a set of session parameters. The situations in which the DSECT might be useful are listed here. For further information about the individual macroinstructions, see Conventions and descriptions of VTAM macroinstructions. For a general discussion of DSECTs, see the introductory section of Control block formats and DSECTs. The format maps and DSECT descriptions for the BIND area are shown in Figure 1 through Table 7.

The term “fixed-length portion of BIND” refers to bytes 0–25 of a BIND area (only fixed-length fields). See Figure 1 for an example of the fixed-length fields of a BIND area. In general, the fields in BIND after the fixed-length portion are variable-length fields, so they cannot be examined by a DSECT. However, in some instances, the primary logical unit name field is padded by VTAM® to be a fixed-length (8-byte) field. In this case, the full ISTDBIND DSECT can be used.

The ISTDBIND DSECT can be used:
  • To examine the session parameters obtained by INQUIRE OPTCD=SESSPARM. The full ISTDBIND DSECT can be used.
  • To set up the session parameters (in the area pointed to by the NIB's BNDAREA field) sent by OPNDST in a BIND request, or sent by OPNSEC in a negotiable BIND response. The full ISTDBIND DSECT can be used.
  • To examine the session parameters pointed to by the fourth word of the SCIP exit routine parameter list when a BIND is received. The full ISTDBIND DSECT can be used.
  • To examine the BIND image portion of a CINIT request unit received in a LOGON exit routine. Only the fixed-length portion (bytes 0–25) of the BIND area can be examined with ISTDBIND. Note that this portion of CINIT can also be accessed by INQUIRE OPTCD=SESSPARM.
  • To examine bytes 1–26 of a BIND request received in an SCIP exit routine. Byte 0 of BIND is the BIND request code and is not included in ISTDBIND. The BIND request is pointed to by the AREA field of the SCIP exit routine read-only RPL.
  • To examine bytes 1–26 of a negotiable BIND response received in the AAREA field specified by OPNDST. Byte 0 of AAREA is the BIND request code and is not included in ISTDBIND.
Figure 1. Format of BNDAREA (ISTDBIND).
The diagram shows the format of BIND area, which contains the field information between displacements 0 and 36.

For BINPSCHR, see Table 4 Table 5, Table 6, and Table 7.

Note: The double outlined section is the fixed-length portion of BIND. The names in brackets are the operands of the MODEENT macro used to build the corresponding fields in a logon mode table entry (refer to the z/OS Communications Server: SNA Resource Definition Reference for information on the logon mode table.) The names in parentheses are the ISTDBIND DSECT labels for the field.

Although the PLU name can be 1-17 bytes in the BIND RU, the ISTDBIND DSECT requires it to be exactly 8 bytes. This causes the offset of the user data field to vary in the BIND RU but not in the BIND DSECT. The area provided by VTAM to the SCIP exit will have an 8 in the PLU name length field and the name may be padded with blanks or truncated, if necessary. VTAM requires the bind area to be in this format when it is supplied by the application on an OPNDST or OPNSEC macroinstruction. Also note that in the case of a BIND error, the offset contained in sense code 0835nnnn is adjusted, if necessary, when given to the application to parse the BIND DSECT.

Note:
  1. The RU size specified should be no larger than the size specified in the received CINIT or BIND RU.
  2. The BIND request unit code (X'31') is not included in the ISTDBIND DSECT.
  3. Certain information is available to an INQUIRE OPTCD=SESSPARM for a received CINIT RU which is not available for other types of INQUIREs for session parameters. This information is the BIND type and user data.
  4. The PLU receive pacing count is not overlaid unless the application program sets BINBPACE to zero in BNDAREA (meaning the application program wants the CINIT value to be used), or unless the value in CINIT for this field is 0 (meaning the SLU to PLU direction is not to be paced). The value specified should be no larger than in the associated received CINIT RU.
  5. The user data and user-data length have different meanings depending on when they are examined:
    • For INQUIRE OPTCD=SESSPARM for a received CINIT RU, they represent the user-data field specified in the original session-initiation request. For other types of INQUIRE, the length field is zero and there is no user data.
    • For OPNDST ACCEPT or ACQUIRE specifying a BNDAREA, they specify the user-data field to be sent in a BIND to the secondary logical unit. If BNDAREA is not specified, no user data is sent to the logical unit as part of BIND.
    • For an SCIP exit routine scheduled by the receipt of a BIND request, they specify the data received in that BIND request.
    • For OPNSEC sending a negotiable BIND response in a BNDAREA, you must specify the user data-length field (and user-data field if the length is not zero) when returning the BIND response to the PLU. If BNDAREA is not specified, no user data is sent to the logical unit.
  6. Note that the cryptographic length field in this byte is always set to 0. Some of the variable-length cryptographic information is available through use of INQUIRE OPTCD=SESSKEY.
  7. VTAM changes the session level cryptography part of this field (if possible) if a higher level of cryptography is required for session establishment.
  8. See NIB PROC option for NEGBIND to see how the application program can set the type field indirectly. The type field of BNDAREA is ignored by VTAM; the format field is tested for 0 by VTAM.
  9. See NIB ENCR parameter to see how the application program can set the session level cryptography part of this field indirectly; that part of the cryptographic-control field in BNDAREA is ignored by VTAM. The private-level-cryptography setting can be changed by the application program in BNDAREA and is not subsequently changed by VTAM.
  10. These are the session parameters pointed to by word 4 of the SCIP exit parameter list, not those in the BIND RU pointed to by the SCIP exit read-only RPL.
  11. The total BIND RU length (request or response) can be no larger than 256 bytes.
  12. This field is checked for valid values by VTAM. The macroinstruction fails if a value that is not valid is found.
  13. The application program can decrease this value, but cannot set it to 0 unless the field received in BIND is 0.
  14. VTAM determines the pacing value from either the definition statement for the LU or the logon mode table entry.
  15. Although the PLU name can be 1-17 bytes in the BIND RU, the ISTDBIND DSECT requires it to be exactly 8 bytes. This causes the offset of the user data field to vary in the BIND RU but not in the BIND DSECT. The area provided by VTAM to the SCIP exit will have an 8 in the PLU name length field and the name may be padded with blanks or truncated, if necessary. VTAM requires the bind area to be in this format when it is supplied by the application on an OPNDST or OPNSEC macroinstruction.
  16. VTAM sets byte 6 bit 6 (Control vectors included indicator) as needed and includes any control vectors appropriate for the session.
