Section 2: Data Area Layouts The following conventions are used in this section: 'e Various versions of the network control program are referred to in the following manner: NCPl - Network Control Program/OS, Version 1 (for OS/MFT and OS/MVT TCAM users) NCP2 - Network Control Program/V5, Version 2 (for OSNS TeAM users) NCP# - Network Control ProgramlVS, (for OSIVS and DOSIVS VTAM user~ latest version) NCP - All versions of the network control program. If a field or bit is not used by all versions of the NCP, the version or versions that use it are shown in parentheses after the field or bit description. For versions not listed, the field or bit is unused. • The displacement of each field from the beginning is given in both decimal and hexadecimal notation (hexadecimal in parentheses). The displacements in the direct addressable areas IXDA, XDB, and XDH) are given in absolute, hexadecimal notation since these are always in a fixed location of storage. • If a single field has dual uses with different labels according to the use. the displace· ment is listed only once, and a broken line followed by the word "or" is inserted between the different labels. • The contents of some fields are designated as shifted addresses. This means that in 3705 configurations larger than 64K, the storage address is shifted right two bit positions before being placed in the data area. Shifted addresses are always in field with a defined length of two bytes. If the controller has less than 64K bytes of storage, the address is not shifted. • Pointers or addresses contained in fields with a defined length of four bytes occupy the last 18 bits of the field. (Only the last 16 bits are significant if controller storage is less than 64K.1 Often byte 0 and the first six bits of byte 1 of these fields are lISed for other purposes, such as for flags. In cases such as these, the four-byte field is shown as follows: B(8) XYZMCBAD Major control block displacement. XVZISKEP Task entry point (last 18 bits) gIg) XYZSCHED "\" " " " " " Task "\ di~p~tching PTloTlty. • Labels shown in parentheses are equated in NCP and EP code to the defined label for a field. Equated labels are most frequently used in the direct addressable areas. • One field in every queue control block (aCB) is labeled "major control block dis· placement". This field contains the offset to the beginning of this aCB from the beginning of the control block that contains the aCB. For example, the DVIMCBD field contains the displacement from the beginning of the device base control block (OVB) to the beginning of the device input aCB. • Bit patterns or hex values within a field are defined in a byte expansion table following the formatted data area. The bytes within a field are numbered from zero origin. For examDle. if the first byte in a two·byte field has a unique definition, it is referred to~~sJ~yte o~ 1 .• Bits in the byte expansions that are not identified are reserved" Data Area Layouts 9
