ARCADEXT Parameter List

Table 1. ARCADEXT Parameter List
Offset	Length or Bit Pattern	Description
00 (X'00')	4	The address of the 140-byte VTOC entry of the data set about to be deleted or retired. If a non-VSAM data set is being deleted or retired from a level 0 volume, this data area contains the real VTOC entry of the data set. If a VSAM data set is being deleted or retired from a level 0 volume, this data area contains the real VTOC entry of the base data object with the base cluster name contained in the first 44 bytes. If a data set is being deleted or retired from a migration volume (DASD or tape), this data area contains a dummy VTOC entry of the data set containing only the following valid fields: Data set name (base cluster name if VSAM) Data set organization Data set indicators (DS1DSIND) Data set creation date Data set expiration date Data set last referred to date Data set block size (non-VSAM) Data set key length (non-VSAM) Data set record format (non-VSAM) The last-referred-to date field can be the same as the creation date if the data set did not have a last-referred-to date when it migrated. The last-referred-to date contains the last update date if a VSAM data set with a last update date is being retired.
04 (X'04')	4	The address of a 6-byte data area. If a data set is being deleted or retired from a level 0 volume, this data area contains the volume serial number of the level 0 volume. If a data set is being deleted or retired from a migration volume, this data area contains the volume serial number of the original level 0 volume that the data set was on before it migrated.
08 (X'08')	4	The address of a fullword binary area containing the approximate size of the data set in units of 1024 bytes. The size is the space available to be allocated for the user's data set. Note: Data set size is based on a 2KB blocking factor for any DASD. This field is only an estimate of size. If the data set is blocked with a factor other than 2048 bytes, available space can be larger or smaller.
12 (X'0C')	4	The address of a 4-byte data area with only the first 3 bits defined. The bits are: 0... .... This data set is being retired. 1... .... This data set is being deleted. .0.. .... The next bit does not contain valid information about the type of volume DFSMShsm is processing. .1.. .... The next bit contains valid information about the type of volume DFSMShsm is processing. ..0. .... A level 0 volume is being processed. ..1. .... A migration volume is being processed.
16 (X'10')	4	The address of a fullword binary return code.
