6.6 VSE/POWER Data

VSE/POWER account data may reside on either disk or tape.
The disk may be either a CMS format minidisk or a VSE format
DASD volume.  If the data is on VSE DASD, it is read from the
'VSE.POWER.ACCOUNT.FILE' dataset (IJAFILE), not from the
POWER spool.  The POWER account file may have a different
name in your installation.  Consult your systems programmer.

VSE/POWER account data can be stored as an OS/MVS simulated
file.  OS/MVS simulated files are files created by OS macros
in programs running in CMS.  These files are maintained on
CMS disks, but in OS format rather than in CMS format.

VSE/POWER account data is contained in unblocked, variable
length records, with a maximum record length of 2,048 bytes.

The records have the following format:


     RDW DS H Record descriptor word
              DS H Reserved
     ACSYSID DS CL1 System Id
     ACTYPE DS BL2 Record type and version
     ACCOMP DS CL8 Component Id '5686005 '
              DS CL5 Reserved
     ACDATE DS CL8 Date
     ACSTRT DS PL4 Start time
     ACSTOP DS PL4 Stop time
     ACUSER DS CL16 User information
     ACNAME DS CL8 Job name

     ACIDEN DS CL1 Record Id
     ACCANC DS BL1 Cancel code
              DS BL1 Reserved

from shared spooling environments.
