SMF Record Layout
The new SMF record layout is in the table below. It specifies the SMF TYPE or is
defaulted to by the new INITPARM (CDHWRTY=XL1’85’=133). It contains a subtype of 2
(CDHWSTY=XL2’0002’), and a subsystem identification of CDHW (CDHWSSI=CL4’CDHW ’) to aid in
identification. The first 24 bytes are the standard SMF record header for records with subtypes. The
remaining bytes are the High Water mark information.
Note: For programs, such as DFSort, that
reference field position rather than field offset, add 1 to the offset for control card usage. For
programs, such as REXX, EXECIO and ISPF BROWSE/EDIT, which do not handle the RDW field, subtract 4
from the offset to calculate field position.
For a sample layout, see the table below. | Offsets | Name | Length | Format | Description | |
